I live in upstate NY and joined one about 3 months ago. My personal experience is that the place is so busy that I would usually have to wait to use some of the machines because the place was packed. It also probably didn't help that I went during the prime times like from 5-7pm during the week nights and mornings on Sat and Sun.
The other thing I didn't like was the place by me advertised it being open 24 hrs but that was only Monday thru Thrus night...that didn't not include Fri, sat or Sun nights which was what I was looking for. I think they close at 7pm on Saturday night.
The place also advertises judge free zone but I found it to be a lot of the younger crowd just kind of a hanging out where the I wouldn't see girls atually working out but just walking around in tight leggings and cropped tank tops showing their stomachs.
I never used the tanning beds at the gym but my girlfriend did and said they were absolutely filthy. My friend always cleaned the beds before and after she used it but stopped because they were so nasty.
Now this is all just my personal opinion and experience.
