Being a pervert and former pornographer I've been around sex communities for many years in various cities. No "sex club," lasts that is "open to all, all the time." Even the Wet Spot, Seattle's sex positive community center, has long ago learned that to attract certain crowds you've got to make an exclusive space for them and has started offering gender and orientation specific parties.
Now there are also parties there that are "open to all," and as a result great chunks of the population don't go when they are scheduled. Why? Because sex parties that lack restrictions on entry very quickly become overly populated with men looking for heterosexual interaction. Once you get a crowd of ten plus guys, all looking for an attractive woman to play with, lots of women, heterosexual couples, gays, and trans folk who are into things other than heterosexual play (and even a good chunk of those who are into that kind of fun) simply won't show up. Or, if they do, they'll take one look around the space and leave. I'm making no moral claim to any superiority or deficiency in that behavior, just pointing out that that is how folk behave, IME.
So if you're really wanting to do a sex camp I'd suggest getting rid of the notion that it'll be for everyone, all the time. Have specific parties and times with themes. Over the course of the event if you want to be "serving everyone," then do so with the range of your parties. But trying to mix the red hankie brigade, say, with your standard group of swingers isn't going to go well. (Red handkerchiefs being a single among the gay male crowd to show who is into anal fisting, for those who don't know.) Instead of simply opening the doors, have a Red Hankie party at time X, and a swinging couples party at time Y.
I'd also suggest you get a committee of perverts that represent the demographic you wish to attract involved in the planning and running of the camp. If you want to truly be something for everyone then get a group of "everyone," together to pull it off. No matter how open minded I, as a largely het male poly swinger and switch who isn't into S&M/B&D, am there is no way I could build an environment that would appeal to hard core leather butch dykes as well as one of their own could. By way of one example.
In terms of safety, orientations for everyone before their first visit is always a good idea. Going over the rules will not only educate folk on what they are, but also that they exist. Publish and post them around the space and have volunteer "hall monitors," that are there to educated and evict if necessary. And it will be so necessary, if you're space becomes popular, I can assure you.
Best of luck!
