I tried the 40 minute introductory session after visiting the dinosaur park next door (also great). It was a small group of just 5 people, mixed ages. The instructor was great - clear, patient and fun. And it's really easy to pick up. We all had personal instruction but we weren't hanging around waiting. Much cheaper than any other similar segway tours I've seen and great fun - we laughed for pretty much the whole time! Will be back for a longer session!
