In reply to stevieb:
I went to the one in Exeter around 3 years ago with a large group of supposedly responsible adults. I seem to remember sort of coercing the staff into trusting us more than they normally do with punters.
I think as a general user you might find it a pain waiting each time as someone comes over to do the clipping for you, but I suppose it depends on how well attended the floor is. From what I remember the staff have an Alan key type thing to do the clipping, so you can't do it yourself.
Some of the climbs/obstacles were pretty amusing, and a bit of a laugh, but probably more cos we weren't actually as responsible as we were supposed to be, and made a bit of a joke of it all.
Sort of hangings you find are towers that ascend, and you jump between them, climbs with rotating holds, jump onto a trapeze, climbing up nets and poles, speed climb challenges, and just basic climbing walls probably like grade 3!
The older kids might not be too thrilled by it, but depends if they're at the grumpy 'cool' stage yet.
I saw the new one in my neck of the woods is around 15 quid for an hour. Pretty pricey for what it is, and that hour will soon pass.
Maybe ask the kids what they think of the idea, there's bound to be a video or two on youtube!
