I visited https://www.booktickets.disneylandparis.com/ and thought of booking tickets for Disneyland but then I found this site 365tickets.com. It's price is little higher but it says something cal FastPass is included. I'm a bit worried to continue since they haven't provided much information about this FastPass.
Is there anyone who has tried this site to book DisneyLand Tickets? And what is this FastPass means?
