Went to HK with a large group of friends. They do have coupons so I do recommend you use them for free transportation from the border though we didn't know till after the fact. The club was english friendly but some of the girls could only utter basic words. Knowing a little spanish goes a long way.
For a big group, it's better to ask for two booths. Otherwise, we almost filled up the entire round booth and there was barely any room for the girls to sit. I did a couple of lap dances but they were pricy compared with a trip arriba. It is comparatively cheaper to buy them a drink and hand them $1 bills.
Amazing experience and will be headed back in a month or so for round 2.
