Are they available at all resorts yet, or just a select few?
I believe it’s still just deluxe resorts. They need more vehicles to handle the demand. That said, some people have reported stopping by a deluxe resort and getting it activated even when staying elsewhere, but others have not. And once the app is activated, it can be used anywhere on property and remains active for future visits.
Enjoy your vacation!
But will they take you from the parks to a nonparticipating resort?
