Opinions needed!

My husband and I will be taking a southern caribbean cruise in January, and we will be stopping at the following ports:

Barbados, Grenada, St. Lucia, Antigua and Tortola. If you had to pick your top two or three dive locations, which stops would you chose? I'd love your input!!!

Norwegian Spirit - January 2005
Grand Princess - May 2003
Norwegian Sun - May 2002
Norwegian Sea - May 2000

Tortola stands out with the dive on the wreck of the Royal Mail Ship, Rhone which sank in 1865 or so. It was the first of the big sailing steamers. Two one tank dives will cover the bow-midsection where you can penetrate the hull. The second dive is in shallow water to see the remaining boilers, stern with hugh propeller and other neat artifacts that still grace the bottom.
