MY RECENT (10/18/2013) EXPERIENCE AT DISNEY RESORT ON SCOOTER (ECV):
I visit the Diusney resort regularly almost every week by myself with a scooter and just tried with the new rules. My biggest observation is that they are sure spending way too much CM time on this. The budget must really be shot. Most attractions have little change for me except for some that now give out written return times instead of waiting in a long line. The only real change is with Star Tours, for which I had to get a fast pass and leave my scooter on the front outside and take the elevator on foot.
All in all, things worked out very well with little noticable change except for all the additional CMs
