Great experience! Our guides, Chris and Leesha (I hope I'm spelling it right) were amazing - cool, knowledgeable, fun and they went out of their way to make it awesome for us!
We had a small kid in our party, who had to go in tandem with a guide on some lines - they were so friendly and helpful. My 11 year old did get stuck on the last line, but they got her out really quick, in less than a minute.
I think it's better to go earlier in the morning - less people and cooler air.
Can't recommend them enough, we had so much fun!
