I’ve seen threads in the past. Perhaps someone will be able to post a link. It’s easier to tell you the ones that your ECV cannot go into.
Here are just a few I can remember:
One at MK that stands out is Pirates of the Caribbean…you have to transfer to a manual wheelchair to go thru the queue.
At Epcot for Spaceship Earth, you park your ECV at the exit and the CM leads a group of handicap along the rail up the ramp to get onto the ride vehicles. I don’t know the process if you can’t walk that distance…probably work with you with a wheelchair.
At HS, if you ride ROTR, don’t give up your ECV the first time they ask you if you cannot stand a while and walk a ways. Tell them you need it all the way to the ride vehicle.
Edit: forgot to add “Spaceship Earth” when talking about Epcot. Sorry.
