The staff are super helpful at this place! I was apprehensive as it was my first time, however the friendly staff readily assisted me with equipment and directions on how to use it, even though they seemed really busy. Whilst I had a great rock climbing experience, my sister who was with me said that the climbs were "too easy". Perhaps it's not a place for the experienced.
I went after work (around 7pm) on a weeknight and it was really packed. Despite this however there were not queues. I have returned to this place many times and would recommend climbing outside 6-8pm if possible.
