HI, We did the Segways in St. Martin in 06! DH, myself and our twins boys (12)! It takes some getting use to, they do let you practice and give you instructions. If I remember right, they took us all the way down the main drag (you can see the ship) by the water until we couldn't go anymore. It gets sandy and the area is a bit run down at that end. Then we turned around and back tracked past where we started and went by a little shopping village (which was interesting)trying to drive it around the carts...lol! It was fun, my boys enjoyed it!!! When you get there go and check it out, we watched others before we decided to do it!!
I don't think I would do it again, once was enough, I am sure my boys would!!!
