This is the model of my personal scooter. My last trip to WDW, it was having a little trouble after a 16 hour day (10 am to 2 am -- I love late night EMH). It still got me where I needed to go, but it was a little slow and hesitant on slopes, and I had to put it in freewheel and push it up the ramp onto the bus. But it handled 10-12 hour days just fine. This was in early December, so crowds were low and I was able to travel fairly fast a lot of the time, so that's a factor too.
