North Beach is the best beach and the one the island is famous for. Suggest getting there by 9 or 10 am to get a beach chair from one of the many beach restaurants. They charge for these chairs or require you spend a certain amount at their restaurant (they all do beach side drinks and food to you).
You can rent a golf cart and explore other parts of the island but if you stay in the north part of the island you can walk everywhere within 10-15 mins. The hotel can help with reserving a golf cart.
