My wife and daughter will be arriving in Paris (traveling by airline from Spain) on Tuesday July 16 and leaving on Sunday July 21st going to London by Train. Seems to me their best Metro option is the Card Navajo, this would seem to fit the Navajo card time frame (Monday thru Sunday), otherwise get packets of Carnet. Can they purchase either the Card Navajo or Carnet at either of the Paris airports?
I know they want to take a day trip to Disneyland Paris, and was wondering 1) if the Card Navajo would get them there without having to pay extra, and 2) how about the Carnet, if they were to go that route, could they get back and forth to Disneyland Paris without paying an additional fare to their Carnet tickets.
My thought was the Card Navajo gives them more flexibility in being able to take more trips, is it more difficult to get a Card Navajo vs. a packet of Carnet, and is a picture require to use with the Card Navajo.
Thank you for any help!
