Excellent points all around! I had to add . . . did you know that if you require a specific kind of bus to accomodate your
ECV, you simply need to tell the concierge at your hotel what you need and where you are going. At the Swan, they required a 45 minute lead time. I understand that at the parks, you tell guest services to request a specific type of bus. Kudos to a lovely woman in an EVC that I met on the boat to MGM for this information, it worked great.
I personally did not have problems at park closing, in that I boarded first and thus there was room and I did not have the pressure of people around while I effortlessly backed in.

(ok, maybe not! but I did get much better once I did it a few times). But I admit that I didn't do it much in my EVC and am used to a folding wc where I get up (also fine in that I sit until time to board).
Cheshire Figment, good point on the car vs. van. On the car vs Disney transport question, if you are going to places where you can go directly, that's one thing, but if you think you'll have to transfer a lot or want to do non-Disney stuff (gasp!) dissassembling the
ECV in the car is a very reasonable option. It is nice to not have to wait and to just do what you want when you want. We went outlet shopping and dined in a variety of hotels (loved the buffet at AKL) and appreciated the car.
I guess what I was trying to say was that the Disney transport is a perfectly viable option, you would not have to rent a van in order to get around in an EVC.
