I have one that I used on a recent trip. I have the hard plastic seat that I added a cushion to. It was ok, but I've ordered the new deluxe seat cushion, which I think is now the standard one instead of the plastic one. (I haven't received the new one yet.)
AK was fine, and I didn't have much trouble with the bumps. For some reason, I had more trouble with the new Star Wars area in HS.
Anyway, the TravelScoot was great through the whole trip. It was definitely a game-changer. I can lift it into a vehicle fully assembled. (It's about 35 pounds.) It definitely made the whole trip more enjoyable. And I didn't have to wait for a wheelchair in the airport, nor did I have to do a meet and greet with a
scooter vendor. Both of those things were a significant improvement.
I wouldn't hesitate to go to Disney with one. My battery indicator never went below two bars. We probably did 6 to 8 miles a day. I have an extra battery, but I haven't needed to use it yet.
