IMHO Curacao Marriott was mediocre. There is now a new Renaissance closer to downtown--but cannot comment about that. http://www.tripadvisor.com/Hotel_Rev...d_Curacao.html

I liked the Marriott St. Kitts--but stayed there many years ago when the property was brand new.

Have seen but not stayed at the Marriotts in Aruba (seems okay) and Grand Cayman (below average).

By far the best Marriott property in that region (not strictly Caribbean) is the JW in Guanacaste, Costa Rica. I would hands down go for this property versus all the rest.
