Ruth, I live close to the resort , If you rent a golf cart to go back and forth to the resort from town its a mistake. if the road is 6 miles ,or 8 mile its still going to seem like a hundred because the road on a golf cart is miserable. If the hotel is suggesting you rent one they are being irresponsible and probably just thinking of the commissions from the golf cart company.
take the Island Ferry its cheap and easy . leaves from your hotels dock every other hour and docks in the center of town.
Diving from the hotel on the other hand is great, much better reef up north and the dive shop on the end of your dock is a good one.
dinners out can be done on the ferry service as well very easy and the ferry runs hourly at night. they will drop you at the dock of the restaurant and pick you up as well.
