Last February, the swim up bartender asked us to wait a minute as he looked around (for security, I believe). Once he was clear, he patted the counter for us to jump up. It did seem to us that it is frowned upon.
In October, at the sexy pool the bartenders (Jose) was pouring shots (not sure of what) over everyone's nipples... this is the day i refer to as Crazy Tuesday. I know he was having a blast with it!! And on the Boob's Cruise... it's all about Whipped Lightening - plenty of it and everywhere!
We were there for our fifth trip in September and saw people doing body shots everyday. Especially with the alcohol infused whipped cream.
I could tell you some of the variations i saw on the boob cruise last year, but it might be censored and you may not believe me,lol.
