On my five cruises, BJ was dealt from an eight deck shoe, double on any two cards, split pairs three times(except aces), double after splitting, and dealer stands on all 17's. With these rules, the house edge is only 0.47% with correct BS. Over the long run you get a lot of play time for low cost. Of course, bad play will significantly increase the house edge.
The best entertainment is often provided by the other players, especially the bad ones. I love to see the look on the dealer's face when somebody splits a pair of fives. I also get some looks of disgust from other players when I hit an ace and seven against the dealer's nine, ten, or ace.
I bet the table minimum to allow myself plenty of room to double and split when the time comes.
