Asking this now for next year. Figure info is still fresh 
Background:
we are planning on NYE in EPCOT next year. My husband has mobility issues. Weakness in his legs that make walking an extra hard effort. He walks slowly and needs to stop often. Also has balance issues occasionally. We really want to enjoy Epcot. Plan is to have three ADRs spread from 1:00 - 11:30. Not planning on attractions and will be hanging in world show place. No transportation issue since we will be at the dolphin. I would rent from a third party. Not going to depend on renting in the park.
Is it unreasonable to think we can navigate world show place on NYE with a wheelchair or is it just too crowded?
thinking wheelchair over scooter - this way he can still walk from time to time. Pushing it will actually aid him in walking. And he will have a place to sit!
Also feel that Nye would not be a good time for a first time scooter user.
Any advice is very welcomed
Thank you!
