Activities are all over.
Contact the Villages sales department and try to get into a Life Style house [program]. It may cost more than the hotel but it's well worth it. They will give you a cart but rent a car too if you are flying in. The golf is amazing all over but I wouldn't spend too much time on the course during a visit. Bring a camera that shoots video and narrate as you shoot. Later this will make a difference. It's so big it can be overwhelming.
