DH and I did the tour last September and LOVED it! We had two excellent guides - one was the Segway/safety instructor and the other covered topics like Disney trivia and facts about FW & WL - they take you to various spots around FW. It was especially fun to take the Segways off road too. The only note of caution I would say is to consider how quickly the people you are thinking about taking can learn something. DH and I took the now defunct Epcot Segway tour several years ago, so getting on the Segway again at FW was like riding a bike - after a few moments I felt completely comfortable since I had done it once before. However, the instruction time before the tour was relatively small and the lady next to me had never been on a Segway before and had a hard time catching on with the relatively small amount of instruction time - to the point where they asked her if she would rather stop and have a refund! But she did mostly catch on and was able to complete the tour.
I know you didn't ask, but we also did the Archery class the same day at FW. Yes, there were kids in the archery class, but DH and I had a blast! We did the later tour in the morning for Segway, went to the Meadows Snack bar for lunch and then walked back over for archery in the afternoon. It was a great day.
