Been there a couple of times. The place itself is good. But as with any swingers club, there are multiple factors that decide whether you have a good time.
How many women/couple visit on a given day is purely down to luck.
Even if they visit, are you charming enough to talk to them and get them to have sex with you?
As for the venue, they have nice facilities - Warm swimming pool, hot tubs, a small porn theatre, dark rooms etc. During day time it's a naturist club. On certain evenings, they have parties which usually have higher attendance.
