Well the big 4 in the Carib are Cayman, Coz, Bonaire and Roatan. You have a chance to check off 2 of them in one cruise :) Cayman has beautiful reefs and a few wrecks, Coz is drift diving, swim thru’s and beautiful viz with I think fewer fish but you’ll probably never see a Splendid Toadfish anywhere else.
How many of you are diving because we have some DB members who operate 6 packs in Cozumel and you could get a better price and go where you want as opposed to the cruise operator who tailor’s the trip to the lowest skill divers.
