We had a blast with Matt, our guide. He taught my wife how to ride in under five minutes. It was a fun time and one I will certainly do again.
We booked a two-hour tour Friday morning at 9 am, and had a a tour group of myself and my three teenage kids. Learning only took about two minutes per person and everyone became an expert after 15 minutes. It's easier than riding a bike or roller skates, and it was no trouble to take cell-phone pics while riding. Our guide, Christopher, was pretty friendly and knowledgeable. He was also very safety-conscious, so I never felt worried about my kids getting hurt. The sights are good, but the fun part is just being able to ride around on Segways.
