In mid-May we are staying at Greenwood Beach Resort for 5 nights. Have read the postings for Cat Island and see where having a car for a day or two is advised, but not where to rent one. Please advise. And is it possible to rent a boat and go out and about the island yourself, or do you need to have a captain? And where would you recommend we rent a boat? Is is possible to visit a nearby island for the day with a captain, or is it too far?
