One of the things that wasn't mentioned by the OP but is something I've seen by some couples looking for this sort of arrangement is exclusiveness. I've also seen that with couples looking for an ongoing thing with other couples. They likely want to minimize the risk of STDs in either case, but limiting things like that kind of defeats the purpose of swinging IMHO. I know we personally tend to avoid any situation where someone is trying to impose some sort of exclusiveness.
Ymichael14 - Just an FYI, Thur & Fri can be difficult date nights for a number of people. Saturdays would likely be the top choice for most people. Not saying you'll have any better success, but just something to consider. Also, someone may want to meet/play but have no interest in attending a fair.
