Take your time & window shop.
Not everyone stays in the first club they joined up with, and there is a ton of diverse clubs to look at. I don't think many owners would have a problem with opening their doors and letting you look around to see if it's the right fit for you. If it turns out that it's not a comfy fit and doesn't have the amenities you're looking for - or too many amenities - then I figure the majority of clubs won't have hard feelings should you decide to move on and check another one out.
It should be fairly apparent whether it's up your alley or not within a couple days. Be sure to check out their club's forum too, as that is usually the backbone of what's going on. Some clubs have websites too, which should give a decent picture of what they're up to.
From large to small, relaxed to hyper-active, mixed tiers to high end only, highly organized to loose and laid back... there's bound to be a club for everyone. And if you run through a handful of clubs and just don't feel it - it's cheap enough to make your own too.
