Hi,
My family has plans to take a graduation vacation to Paris for 6 days and Rome for 3 days, not including flight days. We would like to visit Nice, and London while in Paris. Is this feasible? Also when in Rome we plan to visit Milan or Venice. Would this be feasible as well? Any help would be greatly appreciated. Also any suggestions for travel by train from Rome to Paris would be great. We are starting our trip off in Rome. Thank You

With six days in Paris you can certainly take a day trip to London. Make sure to buy your tickets for the Eurostar train as soon as you can, as the price increases. I do not know the mechanics of traveling from Paris to Nice, but I question whether a day trip is feasible.

With only three days in Rome, I don't see that you have time for side trips. There is more to see in Rome than any other place I have ever visited.

You have to choose.
Either you are in Tome and Paris and visit those cities or you visit something else.

3 days in Rome is too short for the city and 6 days in Paris is just ok.

Going to nice takes half a day.

Nice from Paris, and Milan or Venice from Rome, are not realistic "day" trips.

I think London would make sense only if you started there, trained to Paris, flew to Rome and flew home from there.
But 9 days doesn't give you much time for sightseeing after all of that time spent moving around.

If it was my trip, I'd pick London + Paris or Rome + another destination in Italy.

If you land in Rome, you will won't have much time to see anything at all, after you check into your hotel. Only about 1.5 days, then pack up and get on a train, or fly to Paris or London.

I'd skip Rome for a later date, and start your trip in Paris or London, if possible.

London is spread out all over the place, so you might give more time to see the sights.
Paris is a walkable city, so easy to get around.

Feasible? Probably. Enjoyable? Hardly. It would be both exhausting and expensive to zoom all over Europe in such a short time.

You have no time at all in Rome, basically, once the logistics are accounted for, and certainly no time for day trips, particularly to Milan or Venice. A day trip to London from Paris would work. Nice is not realistic (have you looked at distances on a map?).

You can fly between Rome and Paris. A train would eat severely into your already cramped scedule.

I would pare it down to two destinations, preferaby closer together than Rome and Paris, and fit in one or two daytrips if you must.

As above. You will not have enough time for a somewhat decent visit of Rome. Compared with Rome, there is not much to see at Milan or Nice.
If you want to go by train from Rome to Paris, here are the timetables (valid from December 10th 2017 until June 2018):
Roma Termini dp 17.45 - Verona 20.37/21.34 - Paris ar 9.55
Verona - Paris: overnight train with sleeping cars and board restaurant

If you want to include Venice (with less days in Paris):
Rome dp 17.30 - Venice ar 20.54
or Rome dp 8.50 - Venice ar 12.35
stay at Venice
Venice dp 20.17 - Paris ar 9.55

Thank You All so much for taking out time to help me. I really appreciate every comment. We are in the preliminaries of planning so please keep the suggestions coming. Could someone please let me know if there is an abundance of luxury shopping in Rome? That was one of my primary reasons for going to Venice or Milan. Thank You

JColbert, I fell and broke my wrist at Bulgari in Rome. I'm not a luxury shopper, but you can trip in Rome and land at Bulgari. In fact, they took me inside and gave me water when I fell.

There's more luxury shopping in Rome than in Venice. Rome definitely beats Venice for the number of luxury shops, but Milan may have more.

Milan, where I am right now, has no end of luxury shopping.Not my thing, but it's hard to escape here.

Venice shopping is mostly for tourists on day trips. Milan is heavily into luxury goods as is Rome. I'm not a luxury shopper so would naturally choose Rome . . . .after all, all roads lead to Rome. After I went to the opera at La Scala and saw the Duomo there wasn't a whole lot of Milan remaining.

Lots of luxury shopping in Rome, but you might not have time to do too much shopping with the time you have...
Lots of luxury shopping in Paris and London, however.

If it's luxury shopping you are after, Milan, Paris and London should be your destinations.

travel by train from Rome to Paris

Advice--don't do it. Fly

Out of curiosity, what luxuries do you want to shop for?

Thank You Everyone for the tips and advise.
Hello Gretchen I am looking to purchase a Louis Vuitton Handbag and luggage
Thank You again

Best tip for you. Get a really good paper map so you can see scale and distances of things.
Look at some train schedules.
When figuring travel times, do not count just time in train or plane. Allow plenty of time to get from airport or train station to your hotel and plenty of time to get from your hotel to train station or airports.

If you want to go to London, start there. Train to Paris, plane to Rome, or start in Rome, fly to London, train to Paris.
You have no time for any of those other places, simply too far apart. That is why you need a map and schedules and time tables.

And book those Eurostar London-Paris trains well in advance to get deep discounted fares over walk-up - maybe $100 or more cheaper p.p.! www.eurostar.com - www.seat61.com for great advice on that - for general info on trains (great for easy day trips from bases) checvk www.budgeteuropetravel.com and www.ricksteves.com.

In Paris day trip by RER train to nearby Versailles and or places like Chartres, Reims or even Normandy D-day beachs.

Where are you from?

If you're from the US, you're more likely to be able to do luxury shopping in a major city and purchase what you're looking for less expensively. If you're not from the US, you can probably obtain what you're looking for directly from the retailer and it will ship to you and you will not have to pay VAT.

On your other thread you asked re a day trip from Rome to . . . Greece . . . via <i>ferry</i>.

So as has been mentioned you first need a map and couple of guidebooks before considering any other plans. You need a handle on the distances involved.

Have you booked your flights yet? If not, don't - until you get a better idea of what is practical/doable/feasible.
