Hello,
We are planning for a 6 days trip from Phoenix to LasVegas ,We are flying to Phoenix on Dec 24,2018 and reaching there around 10am and flying back from Vegas on Dec 30 evening(Flight at 7pm)
we will rent a car in Phoenix and need some help in planning this trip,So far we came with the following Itinerary

Day 1(Dec 24)-Arrive in Phoenix around 9.30am,Explore Phoenix for few hours and drive to Sedona for Overnight Stay.
Day 2(Dec25)-Explore Sedona(Pink Jeep tour) and Trail to Cathedral Rock(or someother activity),stay Overnight in Sedona(or williams/Tusayan if possible-GCNP hotels are not available)
Day3(Dec 26)-Drive to GCNP early and drive to Page for Overnight stay.
Day 4(Dec 27)-Antelope Canyon Tour and Horshoe Bend for sunset, overnight stay in page.
Day 5(Dec 28)-Travel to Bryce canyon and stay overnight.
Day 6(Dec 29)-Travel to Zion Canyon and stay overnight.
Day 7(Dec30)-Travel to Las vegas

I know we are close to Travel dates and need some advise on what to add more in the trip (maybe cut Zion from the trip and stay sedona or other places to explore in AZ) and places to stay Overnight.

Appreciate your help and time Beforehand!

I can't think of anything to add. Half a day or less of daylight in each of 3 of the most scenic places I've ever been - GC, Bryce, and Zion hardly seems like enough time to even scratch the surface. Plus your travel is a the time of the shortest days of the year.

Sounds like your goals is to stop by long enough to check these off some "been there" list. This sounds like a good itinerary to accomplish just that.

IMO this is not a good plan - not at this time of year for sure. I just did a short trip to the SW with 2 night GC, 2 nights Lake Powell, 2 nights Zion, but it was at the end of Oct/beginning of Nov when it was a bit warmer and just before/after the time change. (You can check out my trip report) You will have much shorter daylight and colder temps. And the 28th/ 29th/ 30th you will have almost no time to see/do anything .

what do you suggest? 27/28-GC and 29 Bryce?(or skip beyce too)
30th Im just driving to vegas to catch my flight evening(been to vegas october?

You will need to be flexible and keep one eye on the weather. You could do the trip as planned if there is no snow falling during the trip as roads are generally cleared quickly after a storm. If there is a storm then you need to have alternate plans.

I would eliminate Page/Antelope Canyon unless it is sunny and you can be there at/near noon since the sun is low in the sky at this time of year and the canyon is not nearly as spectacular if the sun isn't out bright.

Expect there to be snow in Bryce as it is at a very high elevation, the roads and pull outs for views will be fine unless it is snowing or has been very recently. The trails will probably have snow in any case so do not plan much hiking unless you have yak-trax or the like.

If there is snow, there are things to see in other areas. If it is snowy to the east of Grand Canyon, head west. Visit Hoover Dam, Death Valley (we've enjoyed DV at this time of year several times) and/or in the Vegas area Red Rock Canyon and Valley of Fire. If you can't head north, head south and check the Tucson area for Saguaro NP (sp?). etc.

If the weather is bad, lodging might be a bit hard, but do check for cancellations as others will forego travel so more should be available. If that fails, look near the highway exits at intersection with main roads. Between Page and Bryce, look in Kanab, closer to Vegas look near Hoover Dam or in Laughlin.

I'll hope for nice fair weather and that all goes as planned.

Do you have flights booked ? I would have flown into and out of Las Vegas rather than doing a one-way car rental from Phoenix as it's generally cheaper and only adds a couple hours of driving.

Do you have Pink Jeep tours booked? They are currently sold on on 12/25.

I would recommend cutting back on Page to no more than half a day. Either spend an additional half day in Sedona and then go to Grand Canyon on the 26th (if lodging is available) or spend an extra half day in Bryce or Zion. It's not worth the time to wait around in Page for sunset at Horseshoe Bend.

Yes My flights are booked already ,Rental cars price is almost same in and out to vegas or phoenix to Vegas(bcz per day renal is cheaper in PHX).
Pink jeep tours are booked for 12/24 and 12/25 as of now ,Checking regularly to see if something opens up.Do you recommend any other operators for Jeep tours?
Page is overnight stay after we finish GCNP on 12/26 but Im still trying to get a hotel in the park or Tusayan area so I can even spend next day morning 12/27 in GCNP and then drive to page of Anteloper canyon tour(if possible Horseshoe) then drive to Kanob or someother place for overnight stay on the way to Bryce canyon.
Definitely will not spend much time in Page as suggested but if there is storm then I will have to stop in page and directly visit Zion skipping Bryce .Hopefully weather will be good so my trip goes as planned .
I booked my return flight with southwest so if I want to extend for a day not a big deal .

Be sure to look at both reservation sites for Grand Canyon as Yavapai is not on the same site at the others. If you don't get a cancellation, look at Cameron Trading post which is near the junction of 64 and 89 on the east side of the park as well as Tusayan.

Horseshoe Bend is best in the morning, with the sun at your back, as you are looking toward the west from the overlook.

I love the drive from Page to Bryce/Zion.

I will quickly do Antelope Canyon and spend only half day in page and will leave early to Bryce.Will do hiking in sedona as it is in mid 60's and just do scenic views in Bryce and Zion as suggested if only weather permits.If there is storm in Bryce/Zion will probably skip and drive to death Valley as recommended.
Still not booked by stay in Bryce or Zion yet,Planning to book in Best western Rubys inn .If I don't see a cancellation in GCNP then I will book at Tusayan.
Sedona Pink Jeep tours-Broken arrow are sold out for Dec 24 and Dec 25 they are closed ,Do you recommend any other Jeep tour ?
Thanks for suggestions.

At Zion you will not be permitted to drive your car into the valley, so you'll need to ride the free shuttle bus. Since you are not planning any hiking, one shuttle bus trip up/down the valley on the shuttle should take you no longer than an hour if you don't get off.

Nobody said that you should only do scenic views in Zion. I think you are mixing different opinions and thoughts to get that impression. Take a step back here.

Average high in Sedona in December is 57 F. Average high in Zion in December is 53. If you are comfortable hiking in Sedona weather, you will be equally comfortable in Zion.

Zion and Bryce are not the same parks and do not have the same weather. There will likely be snow at Bryce and just doing scenic views at that park is fine, but you should be able to hike in Zion as it is lower elevation and warmer. The only way you would be restricted from hiking at Zion is if a massive winter storm hit the region, in which case you won't be driving anywhere.

I think you need to look at a map and see where Death Valley is before lining that up as your plan B. If you are at the Grand Canyon and decide to skip Bryce/Zion in favor of Death Valley, it will be a 6.5 hour drive to get to Death Valley. Page is over 7 hours from Death valley. You would spend one full day just driving to Death Valley from either location just to have one day of hiking - that is not a good plan. If there is a major storm in Utah that does not affect Arizona, go back to Sedona, go to Painted Desert/Petrified Forest, but I don't think Death Valley makes sense as a backup plan.

Skip the Jeep tour if you're only in Sedona for one day. If you end up staying extra days in Sedona due to bad weather in Utah, do the Jeep tour during that timeframe.

I will be in Sedona Dec 24(by Noon) and 25th,I'm travelling to GCNP from Sedona on Dec 26 Morning.Due to Low temperatures in Utah I'm planning only one day each in Bryce and Zion if weather permits.

The weather at GCNP will also be cold, winter weather since the elevation of the S. Rim is >6000 ft above sea level. At GCNP, you should expect daytime high temps (around 2-3pm) to reach up to between 40-50 degrees F, and nighttime temperatures to be well below freezing. The low tonight, Dec 12 will be below 20F. I would expect Sedona to be ~10 degrees F warmer, both for the daytime high and nighttime low. The low today is just above the freezing point.

On any given day Zion will be warmer than GCNP - the temperatures are dictated as much by elevation as they are where in the region you are.

So if you are prepared for the cold then this is a great time to visit each of those parks. The visibility will be better than in the summer and crowds will be much less as well.

I was concerned about weather going to Low 20's ,as long as it is 40's during day time we should be good to do hiking .I will consider doing hiking in Zion as the temp. is not bad.
Thank you !

Sorry My bad not looking at what elevation Zion is at , We should be good doing hiking at Zion and only do scenic views in Bryce.
We are going for Page from GCNP ,In case of storm we will skip Bryce and head to Zion from Page.
This is my updated plan and so far I have only booked my stay at Sedona(I will book at other places today)
Dec 24/25-In Sedona
Dec 26-Drive to GCNP from Sedona and overnight at park or Tusayan
Dec 27-Drive to Page from GCNP and do Antelope Canyon Tour(Horseshoe bend is optional) and drive to Kanab or Bryce for stay.
Dec 28-Visit Bryce canyon and then drive to Springdale for Stay
Dec 29-Visit ZNP and overnight stay at springdale
Dec 30-Drive to Vegas to fly out

I considered plan B as Death Valley is I have enough time when I skip Bryce/Zion,Now that I don't want to skip Zion I will rule out driving to Death Valley.
Thank you !

I'm just going to repost this since it looks like you skipped over my post:
Average high in Sedona in December is 57 F. Average high in Zion in December is 53. If you are comfortable hiking in Sedona weather, you will be equally comfortable in Zion.

"Due to Low temperatures in Utah I'm planning only one day each in Bryce and Zion if weather permits."

Bryce can be a short stop over - depending on the weather. You could spend as few as a couple of hours at/near the Lodge and see all the views and have a nice lunch. You don't need to stay overnight there since your time is so short.

IMO you really (REALLY) should spend more time at Zion - I'd do two nights there. The weather should be great for walking/hiking.

Thats what I thought but I might end up in Bryce in the evening after Visting Antelope Canyon so I'm planning stay overnight close to Bryce will help me visit Bryce early in the day and then head to Zion.

I replied to your earlier post actually ,Reposting below again
