Yes, we tried one of the "reputable" online swingers clubs in Dublin that organise events... was bad, pitched as a penthouse party, more like a cheap student flat, number of somewhat creepy single guys, a 10 yr old would have organised a better event... safe to say it put us off.... there are no onsite clubs in Dublin and I'm not sure about the one in Limerick, it's located in an industrial estate, does not fill me with lots of confidence, hence we prefer to hop on a plane and experience a top class premises...
Also, Ireland is small, everyone knows everyone, sure to bump into someone you know lol : )
