Can anyone share their ECV and US/IOA experiences? We will be making a day trip with the 2 park 1 day passes with transfers on our trip. We have only been once before and that was in 2007 and it was a day trip as well. It was pretty horrible but I blame that most in part because it was day 7 of a 10 day commando trip and we had just did way to much. I also hated the having to get a locker at so many ride crap. This will be my first trip needing an ECV since I have MS and the heat, fatigue and balance issues would be a real problem with out one. So any advice or tips are greatly appreciated.
