It's A LOT of fun, no doubt. You have to go with a woman or you'll probably be a spectator

When you go with a woman, you have someone to bring to the table.  You can go to the "couples room" where all of the action is.  You can join other couples and it is really fun.  

It's important that the escort be willing to play with others.  I know some escorts will only play with their client.  That doesn't work too well because when there is interaction with another couple, it won't last if all four people aren't having fun.

When all four parties are having fun, in my opinion you can have an encounter that is super real and deeply satisfying, because most of the people there really want to be there.

I've been to the swinger's club many times and only once had a hard time finding a couple or another girl to play with us.  It was on a Thursday, I think.  I advised the client that it was slower during the week and he still wanted to go.  It's best on Friday and Saturday when there are plenty of couples to interact with.

Even just watching everyone else fucking around within arms reach is very hot.  

I've also watched a few gang bangs there.
