Reply #9: Between the two, Grand Cayman

[Scooter24]

But both are very popular choices in the Caribbean and on certain days during the week can attract as many as 8000-10000 cruise passengers.

I'd suggest taking a look at St. Maarten. You will still get some traffic from cruise passengers but not nearly as many as you will find in St. Thomas or Grand Cayman. There is this secluded island off the north coast (French side) called Pinel Island, and it's truly paradise.

These are from our trip there this past October.
