My membership runs out in November. And although I think it's a lovely gym and I have no complaints about it, it's very expensive. I mostly do body pump and spin classes, which I could easily do at another local gym which is also nice, a bit smaller and a lot cheaper! And also I don't use the spa facilities at all.
The thing I'm concerned about though is that I've heard they make it difficult for you to leave. Is this true? Do you just have to write a letter telling them you wish to cancel?
