If you're a beginner, I highly recommend doing the rock climbing here over bouldering. We started off at the bouldering section, because the instructions for the rock climbing only happened on the hour (e.g. 6pm, 7pm etc).
On a weekday night around 6:15pm, it was not that crowded on the bouldering side, which was great. I find the rocks don't have as easy grips compared to The Hub (even at the VB/V0/V1 levels), so it might be discouraging for beginner's-level ppl like me.
In terms of rock climbing, the instructions we received here were WAY better than any other places. By the end, you would feel very comfortable tying the knots on the ropes and would have mastered the basics of belaying. There is such a variety of levels to try out, and I would say an average person who has maybe done at least once or twice rock climbing could comfortably do a level 5.5 or 5.6 top-rope.
If you're new to this facility, the one-month membership (includes one hour introductory lesson) is probably your best deal.
