Acapulco- 1 night
I don't know if you're just there for a night or not. A must see is the cliff divers at La Quebrada. There is a restaurant called La Perla, our host greased the staff a few bucks and we got front row center, in the evening. This was a number of years ago, not sure of the menu, I remember having grilled shrimp. Check out Frommer's Acapulco on line for suggestions.
