Califgirl...I am excited to read that it's a great tour! They have been talking about this tour for over a year. Some questions! When you finally get to ride the segway in the park, is the tour guide giving information about the park? Can you bring a camera with you? I take it you shouldn't have a fanny pack, or small purse over the shoulder? Did you feel it was easy to learn? I can't wait!
Woo Hoo jacksparrowfan, I think you will love this tour. The Segways are very easy to ride. They are very intuitive. If you lean forward, you go forward, if you turn your shoulders and lean to the side, like you're looking at where you're going, you go to the side. You can make a 360 degree circle with the center wheel staying in place, so it's easy to manuever in 'tight spots' (which they never put you in, but it's fun to do all the same

) The Segways are set so they can't go anyfaster than 5 mph, so going out of control is not much of an issue.

Once you have learned to ride the Segway (which is fun all by itself) you get a guided tour of the park with the guides telling you tidbits and trivia about the locations and attractions. You also get some freestyle riding time at Paradise Pier (try riding down the Sun Wheel queue - whee!) The park iseems like it is made for Segways, it is smooth and wide open. It was a very enjoyable experience.
You can not have anything around your neck or over your shoulder for the tour. I had a small camera bag that attatched to my belt, so that is how I was able to bring my camera. I
think a small fanny pack would be ok, but no one in our group had one, so I am not positive. You don't want anything to get in your way or upset your balance, the Segways are pretty sensitive to balance changes, which makes them very easy to ride. We ended up getting a locker for our stuff, but we were one of the very first tours with paying guests, so I'm not sure what they are doing now. The Segways in Epcot have a little carry bag on them, and they don't at DCA.
This tour had things that the Epcot tour didn't - we got a continental breakfast, a group photo and like Epcot, a special Segway Pin.
*sings to the beach boys tune* "Everybody go Cruzin', Cruzin' DCA"!
