I've done the Original Downtown tour with Segway in Paradise 3 times now. I'm not a crazy segway addict, but I think it's a great way to show friends the city when they come visit. The frustrating thing is that all 3 times were completely different experiences depending on the tour guide-- both in terms of the content (amount of city trivia, history, etc) and enjoyability of the ride for new users (knowing they won't get hit by cars or anything if they're not in some crazy rush to keep up.) One was fantastic, another "pretty good", and the other pretty mediocre-- to put it generously. As a participant, I'm not sure there's a good solution since you have no say in who does the tour beforehand. Overall a good time though; I'll probably still bring people there, I just wish it was more reliably awesome.
