I'd love any answers to this too, as I'd like to do it next month...
It seems "odd" that out of $40 they'd give you $30 worth of drinks - kind of like "too good to be true" type of thing, and I'd really like to know if it actually is good.
I've stayed there before, but MANY years ago (1994) before it was Hilton, and the beach was in a good location to the cruise ships (we walked over to see if a certain cruise director was on board that I had, uh, met, years before). Nice quick walk.
