It was ok...glad we did it but wouldn't do it again, or even recommend it to anyone else. The GPS screen was on low so we couldn't see the map. Finally figured out how to brighten it up, but after being stressed about the directions. The volume wasn't high enough and came in and out. The agents, or the tour guide, did not let us know about the "red" and the "blue" routes. We kept following the directions but finally realized we were way to far out for the 1 hour tour. The GPS map confusingly shows all routes, for all lengths of tours. It should only show the route that you reserved. We were stressed again about getting back on time because we kept following, unknowingly, the longer route. We were 2 adults...115 pounds and 195 pounds and it was super scrunched. The driver had a hard time driving because of how narrow the seats were. And it's not made for someone over 5'11". The drivers legs got cramped, again because of the narrow cock pit. Helmets are required, unlike what the pictures show.
