My family will be in Paris from December 26th to December 30th. We are flying into Charles de Gaulle airport and staying at Disney's Sequoia Lodge. Loose plans are to visit Paris on the 27th, Versaille on the 28th, and Disneyland Paris on the 29th. What, if any, transportation passes should I purchase? I appreciate any other suggestions or tips. I have been reading the Rick Steves books, but this trip came up rather last minute.
Thanks in advance!
