Breakfast and lunch at Ak Bol Retreat should not be missed. Very friendly people/owners with a small bar right on the beach. You will pass it on your way to and from town (it is south of you near the Palapa Bar). Lazy Croc BBQ on the weekends is yummy too (on the "road" - look for signs).
If it rains really hard before you arrive, I'd check the condition of the road before renting a golf cart.
Have a great time.
