Hello, Derek!
How exciting your visit to Walt Disney World Resort is just days away! If you have a valid handicap parking placard, then you are welcome to park in the designated areas. Just show the parking Cast Members you have a valid permit and they will direct you. Otherwise, you will need to park in the standard
self parking areas. Courtesy trams available to transport Guests from the main parking lots to the entrances to
Epcot,
Disney's Hollywood Studios, and
Disney’s Animal Kingdom and to the Transportation and Ticket Center where you can access the monorail or ferry to the
Magic Kingdom. In my experience, Guests must step up into the tram, and those with wheelchairs or strollers must fold them before entering. Guests using ECV units will need to drive their units to the entrances or the loading areas at Ticket and Transportation Center. Your wife should have no issues driving her scooter onto the monorail or ferry, as both offer ramp accessibility.
I hope this helps! I hope you make many unforgettable memories during your vacation, and if you have additional questions, please let us know!
Have a magical day!
Missy
