Oh yes, at every party I've been to theres been at least 5 girls from the swinging scene, all first class girls and they always seem to be own there own! I don't think I've ever seen a couple partying there though!
I assume that those girs are the ones who get paid as hostesses and are not visitors. I think the OP is asking if there has been a female punter at the venue now that men and women can attend.
I have been to the new setup (and old LMP) few times, and have not seen any additional girls beyond their expected roster. In fact, 2 out of the 3 times this year that I have attended, there have been fewer girls than advertised, which (although they maintain a maximum m:f ratio) is rather annoying when you choose to go on a specific day based on the advertised schedule, only to find out at arrival that 2 girls have dropped out.
Its a great venue and party, but this does get a bit annoying. Surprised I have not seen a post about the issue here.
