Fruity drink machines always seem to be on the low side when it comes to the booze if you're talking about the frozen mix kind.
Beer is ok, but then you gotta use the bathroom. Not fun when you board DD and then you gotta go.
The Long Island Ice Teas are good and pack a punch. This is your best bet because you can see the bar tender pouring the shots into the glass.
Other way to save money is bring a bottle of rum, buy coke at the hotel, and slam a few in the hotel room before walking over. Then buy a couple drinks in the park. I realize you are probably flying down. It's not illegal to bring booze on a plane. Or if you have the rental car, hit a grocery store (Publix), buy the styrofoam cooler, and pack it with beers and snacks.
