This is an website/app that you can use to rent a car from someone. It's like Airbnb but for cars. You find a car you like and is available for the days you want it and the host gets it ready for you. They will drop it off at a location and you pick it up and drop it back off where they say. You do need a valid license as they will ask for it and you remember to take pictures on the app of all the damage to the car already there so it's documented. Tried it once while there and it worked out well :)
Many hotels and resorts offer snorkeling as an activity. Swim with the fish and turtles of the Ocean in perfect tranquility.
Many hotels and resorts offer swimming with dolphins as an activity.
There are many Luau’s to chose from, some hotels and resorts might have them as well. We will be having one as our welcome party but if you are unable to attend on that day you should definitely look into doing one while you're there for a great experience.
