Apart from working on a tour boat for 2 days, I took the opportunity of taking a circumnavigation around Antigua.
We cruised around the island and we previewed to alot of interesting places.
We then stopped at a private beach, went on hikes, ate lunch, drank booze and went scuba diving with some cool scuba diving machines like the ones in Lara Crofts movie Cradle of Life.
I would recommend a circumnavigation to anyone, not only is it entertaining but you learn alot about the particular place as well.
