My friend and I were visiting MK on Nov. 27th. We both rented Disney ECV's for the first time and used them with ease all day long. The CM told us they were only two months old, and we found them extremely helpful and necessary as we both have had knee replacements and couldn't have toured the park without them. When the MVMCP crowd started entering the park and it grew dark, we realized we needed to depart as we didn't have tickets for MVMCP. We got caught in the huge crowd and gazing at the beauty of the castle caused my friend to lose her attention to her driving. (This was her first trip ever to WDW and it was her sixtieth birthday!) She didn't see the curb that goes around the hub between the castle and Main Street. She accidentally drove off the curb, the ECV fell over and trapped her beneath it. I stared in horror afraid she must have broken something and wondering how to get her and the machine upright. Fortunately, several guests and a CMimmediately rushed to her aid and many helped her up as well as getting the machine back on its wheels. As it turned out, her guardian angels must have been present as she only got bruises. I am posting this to caution everyone new to riding ECV's to be fully aware at all times of where there might be a curb in any of the parks. Please don't take your attention off your driving for even a second and even if you are traveling very slowly as we were.
