My wife an I just got back from our 2nd trip to Walt Disney World this summer.  By far the coolest thing we did this time was taking the Around the World at Epcot tour.  It's a two hour experience which gives you an opportunity to experience the World Showcase before it opens to the public.  Oh, and it takes place entirely on Segway's.  Too Cool!

The tour starts out with a 45 minute training session which covers the basics of Segway riding that you will need in the park.  After that, you quickly ride through Future World and into the World Showcase.  From there on, you get to ride around all of the countries.  There is even an opportunity for photographs and videotaping outside of the Italy pavilion.  Highly recommended.

I really enjoyed the experience of riding the Segway for an extended period of time.  By the end of the tour, I was really getting the hang of it and was doing fairly complicated manuvers.  It took a surprising amount of time to get proficiant with turning and going up and down inclines.  I wish I had a reason to justify buying one.  Do I think it will change the world?  Probably not, but it was fun.
