We did the Segway tour in Epcot last April. It was great. It started before the park opened with training and then they brought you into World Showcase before it opened. Yes, I agree that touring WS was great before the park opened. We are scheduled to do this tour again July 4th at 8:30am. They one at FW is supposed to be a kind of "off road" tour. Not sure how much I would like it but my boyfriends 18 year old son (who did it with us last April and will be taking it with us on July 4th) thinks the off road experience would be exciting. Not sure exactially how much "off road" it is but as we have already done the one in Epcot we would like to try something different.
Also, just as an FYI, we did get a special Segway pin that you only get when you take the two hour tour.
