My transportation to Disney Land Paris is taken care of. But I'm thinking our best option back to the airport will be the VEA shuttle service. Does anyone know if this is something we can wait to book until say, the day we arrive? (we are there for a week) or does this need to be taken care of before hand? I don't want to book RIGHT now because it says you will not get your money back if cancelled so I don't want to take a risk on this just yet (the rest of our trip has travel insurance but this shuttle part would be all on me) I'm wondering if it's casual enough to just take care of on our first day there.
