My son had his birthday 'party' here with four of his friends. We used the whole 2 hours ($100) for rock climbing. All of the staff were really great with the boys, _except_ for their 'instructor.' He really did not instruct them at all. He basically just stood there belaying, and offered no advice to them on how to climb or anything. He did manage to shout advice to other nearby climbers however, which further confused the boys. Once I started yelling encouragement and advice (and I know nothing about rock climbing), he finally engaged, but by then our time was up. The boys were well behaved, so I'm not sure what his problem was, but he missed an opportunity to gain future rock-climbing customers.
