Hi there - While I haven't BEEN to Paris or London - yet! I've been working on planning a trip for next April for a month or so now. You will have more time than we will so you may not need to be as rushed as I will.
In a nutshell - here's what I've learned.
- Easy to take the train from Paris to DLRP.
- Mon & Tuesday - each day has something closed in Paris...so we're using those 2 days for DLRP
- The Euro-tunnel ride to London only takes 2 1/2 hours
- Driving in Paris is ok, parking is expensive and a big huge pain. If you're just going to see DLRP and Paris use their public transport, seems so much better.
- Driving in London - forget it...I think if I did that, I might just get run over!
My plan is pretty condensed..but here's mine - still a work in progress
Leave Chicago Tuesday night - arrive in Toulouse, France Wed am
Wed - Toulouse
Thursday - Toulouse & Carcassonne
Fri & Sat - 2010 Theatre on Ice World Championships (thus the real reason for this trip)
Sunday - Leave for Paris (not sure yet whether we fly (quick) or train (6 hours)
Monday - DLRP
Tuesday - DLRP - although I think we will stay in Paris
Wed - The Louve, Arc, NOtre Dame, St Chapell
Thurs - Eiffel, Orsay museum, & Versailles (if we get up early enough)
Friday - leave for London early, (perhaps do a bus tour) Westminster, Tower of London, Eye
Saturday - Buckingham Palace, Tower Bridge -
Sunday - leave London - fly home to Chicago.
Obviously that's still a rough plan. But I've learned:
Buying a Museum Pass for Paris saves time and money
Buy a carnet of tickets for rail instead of one by one
The Batobus company does a nice land/Seine river tour
TheLouve is closed Mon & THe Orsay closed Tues
The changing of the guard happens at 11:30 daily except when I'm going, it's every other day...so I'llhave to plan that still.
London duck tours looks fun for the kiddos
the tube stop for Abbey Road is St Johns Wood
I literally have a legal pad with oodles of notes...Rick Steves has a nice website with a lot of information.
I hope I helped a little!
happy Planning!
