I lived in Florida long enough to know that these type of laws/rules are passed because only the old people have the time to vote and the youngins don't care enough (until these type of laws pass, then they complain). I know I did. You can't fight them, so I moved out.
I don't think they shut down the operation. They just can't run those trips out of the city marina. Since it is a government run marina, I can understand why they'd want to avoid being misconstrued as supporting an adult entertainment venture.
I really just posted because I think the concept is quite near genius as you give a value added benefit to a predominantly male excursion.
