Please give suggestions for changes, additions, or deletions from my itinerary.
Planning early for a trip in December

Day 1
Flight arrives at 8:30 a.m.
Use Carmel Limo for a car service to Westin in Times Square to store luggage
Rockefeller Center ~ NBC Tour, Ice Skate, Early Dinner at the Sea Grille or Rock Center Cafe ~ better choice?
Radio City Music Hall Christmas Spectacular 8:00 p.m. (already have tickets)

Day 2
Morning in Central Park ~ Zoo, Carriage Ride
Eat lunch either at The Boathouse or in the MET Restaurant ~ better choice?
MET Museum
Fifth Avenue
Trump Tower
Serendipities ~ Dinner, Share dessert

Day 3
Not sure if these sites are too far apart to see in one day...
Statue of Liberty (What is the best way to see the SOL?) (not visiting Ellis Island on this trip)
World Trade Center Memorial Site
MOMA ~ would like to arrive around 3:30 for the FREE Friday time at 4:00
Empire State Building
Dinner Suggestions?

Day 4
China Town / SoHo / Greenwich Village / Little Italy (not necessarily in this order)
See The Lion King on Broadway

Day 5
No Plans Yet...what should I add?

Day 6
Flight leaves at 10 a.m.

The Sea Grill has better food than Rock Ctr. Cafe but it's also pricier.

Walking Central Park and then going to the Met might be a bit too much walking. The Met is HUGE. Also, keep in mind the Met is open late on Fri. and Sat. nights and has live music at that time. YOu might want to use daytime for other things you can't do at night. Pace yourselves.

The "best" way to see SOL depends on you. The fastest is to take the Staten Island ferry for free and see it from a distance. But if you want to go inside the statue, probably the best way is reserving a tour ahead. Just make sure to allow enough time for security etc. People report on the first tour of the day (8:45 am) is fastest and easiest.

The ferries (either Staten Island or SOL) are not far from the WTC site, alll downtown near Wall St. When you go to WTC site, don't miss St. Paul's Chapel nearby.

Both MOMA and ESB are in midtown, but about 20 blocks apart. ESB is time consuming. Buy tickets online in advance to save time on that line. MOMA get very crowded on free Fris.

The best restaurant near"ish" ESB is Artisinal, French Brasserie specializing in cheeses.

You haven't mentioned Top of the Rock which is the new observatory at Rockefeller Center. You could do this on your first day. You can buy tickets ahead online, but there are reports that people are handing out 10% off coupons near the venue. Don't know if that will be the case at Xmas time.

You might want to consider the bus tour that shows the Xmas lights. Here's a guide from last year on Xmas concerts, activites etc.

You should check the event calendar also on nycvisit.com and see if anything is happening during your stay that interests you. You mention Trump Tower (which doesn't have all that much of interest inside). The Time Warner building is great and has some nice shops...as close as NYC gets to an indoor mall.

You might want to consider a fancy afternoon tea. The one at the St. Regis Hotel is very good.

You MUST go to Grand Central Terminal, both to see the terminal and there's a Xmas market there.

Thanks! I made some changes in my itinerary thanks to your suggestions!

A couple of specific questions:
1. What is a good breakfast place in or near Times Square? Just for quick breakfast items like bagels and such.
2. Restaurant suggestions near Wall Street for lunch?
3. Restaurant suggestions near MOMA for dinner?
4. Recommendations for any activities on Christmas Eve Day/evening? I was thinking of going to either the ESB or Top of the Rock along with Grand Central Terminal. Not sure what else I should plan that day.
5. Considering using Carmel Car Service to and from LGA, however I read a review on Fodors about someone having to wait an hour and a half past their scheduled time...is this common for car services?
6. I tend to use mostly a credit card on trips...how much cash should I carry daily for cab fare, etc. if I will probably mostly take the subway?

For lunch near Wall Street, I would suggest Mangia at 40 Wall Street (in the bottom of the Trump Building). It's an upscale deli/cafe that I used to eat lunch in everyday when I worked on Wall Street. There is a Lenny's Deli on John Street that is also quite good. It's a chain, but there's a Hale and Hearty on Beaver Street, I think.

The best way to see the Statue of Liberty is the (free) Staten Island ferry. It goes right past it (both ways).

1. Usually, the best bagel places are not eat in but take out. Some coffee shops in the TS area for a decent sit down breakfast are:
The Red Flame Coffee shop 44 st b/w 5th & 6th
The Art Cafe on Broadway & 52 st,
Cafe Edison
but not sure any of these are great for bagels. For bagels, Bagelfeller on 48th b/w 5th & 6th.

2. There are dozens of places "near Wall st." Have a look on menupages.com (in financial district) Chinatown is also near Wall St. Gee Whiz diner is good but so is Bayards (fancy and pricey).

3. Again, it would help if you said price, type of food/ambiance etc. La Bonne Soup is an inexpensive, casual but good place near MOMA. Michael's is very good, expensive, California cuisine. Abbocatto is good Italian. And the restaurant in MOMA is very popular and trendy.

4. Some theaters will have performances on one or the other. Closer to the time, playbill.com will list holiday schedules. The Christmas Spectacular at Radio City is another option. Several blockbuster movies also open on Xmas eve/day and that's always a good option. ESB and/or Top of the Rock would be fine. Skating in Central Park and ofcourse a nice meal.

5. Carmel is generally fine. If they don't show up within a reasonable amount of time, just get a taxi. You don't pay in advance nor, to my knowledge do they ask for credit card info. You can phone them and say you're done waiting.

6. Have no idea but there are ATMS everywhere to replenish money.

Restaurants near MOMA?

Brasserie LCB (5th bet. 5th and 6th) is a quintessential French brasserie in NYC, long white-aproned all-French staff, that still serves some of the best classic French in the city. Their cassoulet is a classic.

I've noit eaten at the Modern (restaurant in the MOMA), but have eaten twice at the Bar at the Modern. Very good Alsatian-inspired dishes in a MOMA-like surrounding/atmosphere (of course!).

I've eaten at Michael's twice (once invited on business and as part of a wine-tasting group that I belong in) and, finally, our group unanimously decided not to do a repeat tasting in the restaurant as the dishes just didn't do it for us.

Sorry for the typo - Brasserie LCB is on 55th between 5th and 6th.

Great Suggestions! I already have tickets to see The Christmas Spectacular on Dec. 20, so I will watch for theater choices on Xmas eve. I would be interested in moderate pricing for lunch & pricier menus for dinner. Any type of food/ambiance is fine as well.

Christmas Eve is on a Sunday this year so some possibilities may be closed, like theater venues that are usually dark on Sunday nights.
