We were also on the 8/3 cruise and saw the Segway in action. The makers of the Segway has let Disney be the first company to test and demo their product. Disney is thinking of using them at the parks, etc. to get their CM's from one place to another (heard this directly from a CM).
There were offering demos/rides on this up on Deck 10 for $20. for either 10 or 15 minutes. It was pretty cool seeing one of the CM's use it all around deck 10. We even saw one of them using it on Key West to get around town.
It looks like a scooter, but with one axel and two large wheels. You stand upright on it and are able to balance because of the gyros inside it. It is pretty neat.
They also had a photo session in the Atrium Lobby if you wanted your picture standing on it.
A few months ago, if you remember, the Segway made a big intro in the media. It was all hush, hush, and no one knew what the new personal transportation vehicle would look like. They counted down the days and then displayed it. It was on all the early morning talk shows. I clearly remember all the hype a few months ago.
