I did the tour in December of 2004. I had so much fun with it, and I have
the obligatory picture of me on it with SpaceShip Earth in the background.
If you have a Disney Visa, there was a better discount than the Annual
Passholder discount. I think
AAA, AP, and Disney Visa were the only
discounts offered.
Always book it far in advance by calling 407-WDW-PLAY. I recommend
booking early because there are only about 10 spots per tour and only
two tours per day (for the one that goes through World Showcase).
I would love another tour, and I did read a rumor that they will have an
"off road" Segway experience in Fort Wilderness.
Many of us suggested an intermediate tour for those of us who were
comfortable on the first tour, or a tour in other parks.
