Take your time when u get there. Dont go with the first girl you see.
dont tell the girls its your first time.
Question the girl on what services she provides, and confirm it all with her before u go into the room.
If you seem shrewd you will get much better service that some guy who appears too casual.
wear a watch, cos if girls see it they wont try and con you on time. Lately there have been many reports on other forums, of the girls trying to claim 20 mintues is 30 minutes.
If a girl gives really bad service , dont be afraid to complain or at least threaten it.
Sorry to sound too serious Kerry man, but that club has had some bad reports in the last year, and it seems service is slipping there. BUT if you take my advice you should still have a blast.
