As far as food/beverage was concerned there were no additional packages available. You could upgrade the style of your room if you wanted, which i did. So I had a jacuzzi style tub in my bathroom, and direct access to the pool from my room. Literally just opened the back door, and the back porch area was touching the pool. Alcohol that was included had things like bacardi and captain morgan for rum, smirnoff for vodka, bombay for gin, and things around that level. No Grey-Goose or anything i'd consider 'top shelf'. The beer on tap was Corona, but it was surprisingly good and much better than what I've had in the states. And they had a beer called 'Modelo' in cans which was ok.
I felt very safe on the resort. I only went down for a long weekend getaway though, so I didn't leave to go 'see the sights' so I can't say anything about the surrounding areas.
There were a bunch of buffet style restaurants which were open all day and did not require any dress code or reservations. For dinner though there were 6-8 different places that did require reservations and a slightly better dress code. Slacks a nice shirt was fine, tie and jacket were not required. The food everywhere was fantastic.
