So I came back here after having a grand time at recent Yelp event. It was of course a bit different not having sections of this place blocked off for our use, which meant that we had to share a lot of the space with the hordes of middle school (high school?) kids that were climbing and receiving instruction. We didn't get to climb "The Dragon" more than one try, as we had to wait a while for 2 large groups of these kids to finish, after the staff member leading them essentially cut in front of us to do his orientation.
While the climbing itself was as fun and challenging as last time, I can't rate this place as high as I would have given the poor-ish customer service we received to end the night. The discount coupon we used was apparently not calculated properly by one of their staff, which meant that some of our group had to pay more for our entry then expected (and suggested). After realizing their mistake, and deciding to 'fix' this, they required other members of our group to come back and actually pay MORE. The whole thing left a bit of a bad taste in our mouths to be honest, especially since the error was made on their own part, and the coupon was also somewhat misleading.
I would still recommend trying hub-climbing sometime, as it is a lot of fun, physically-challenging, and a great activity for a group of friends...but it's not the kind of activity I expect to try too often given the somewhat pricey fee.
