If you do the all-inclusive option, you won't need a car. If you don't do the all-inclusive, a car is very handy to have, but not essential. If you want to travel offsite, the resort has a shuttle that will take you into the local town for $5 pp return. If you want to rent a car for part of your stay, there is a company onsite. There are also several tour companies onsite for day trips. Or I can connect you with one of the private operators.
