I did the Segway tour last summer and it was excellent. I loved every minute of it. The 1st hour is training in a private room in Innoventions. It doesn't take an hour to master as it's very easy, but they are thorough and try you out in various scenarios.
The 2nd hour is the real fun! In WS from 10am til 11, before opening. You do see some guests just outside it as you make your way there and I remember having photos taken and lots of oohs and aahs. One lady thought we were new CM's being trained! You go all the way round WS and in and out of some of the countries too.
I'd highly recommend it.
Any questions, just fire away and I'll try my best to answer.
