On our last trip with my grandparents one preferred the ECV and the other a wheelchair. We had the experience of using both on one trip. I only mention this if there is a need for you to ever board a Disney bus--you have to do all the backing and whatnot yourself and it is tougher than it looks. If you are a first time ECV user, then it could be a problem. If you have someone willing to push, as we were, the wheelchair was so much easier to deal with. Most of the lines are compliant now, so there's no heading to the front, unless you obtain a red Guest Assitance Pass from Guest Services, which designates how many are in your party, but that only applies on a few rides. Also, when you watch Illuminations, there is seating for those unable to view the fireworks while standing, so you don't get blocked--it was a thoughtful touch my grandparents really appreciated-check it out. That said, stick close to the curbs if you're driving the ECV and put your family on the outside of you-it keeps people from cutting you off, and creates a barrier that will make driving easier through the hordes of people, and reduce your stress. Either way you decide to go, you'll still have a great time as my octogenarian grandparents (who were doubting Disney lovers!) quickly realized. The pixie dust was in no way diminished--have a great time!
