We did our best to make the most of it. Mostly, touristy crap. Rented a car from Celebrity rentals. Terrible company. Don't rent from them. The car had 187,000 miles on it. It didn't steer right, arm rest was broken, a/c worked intermittently and the seats were full of sand. I don't think that it had been cleaned in weeks. The island is desolate and not much to see. There are some cool caves about 20 miles from the dock. We went there and enjoyed that. Other than that, this is not worth the time.
We went to the Pirate museum, which was fun. We also took a cab around the city, also fun. Lots of folks trying to sell you junk. It would have been better to spend a few days there. Atlantis is not worth it. Extremely crowded, long lines, very expensive.
