From the comments here, it sounds like you can't go wrong with any of the Couples resorts. Though all the resorts have their own character, the common thread is great customer service, great food & drinks, cleanliness, and lovely surroundings. Those are the most important ingredients for a vacation and the same at each resort. What really impresses me is the number of loyal customers--that speaks volumes!
We love the all-inclusive experience and have been five times to the DR, and 3 times to Mexico, but this will be our first extended stay in Jamaica. We made a cruise stop several years ago, and I loved the beauty of Jamaica. We are going to CTI in exactly three weeks and can't wait to experience Jamaica and Couples!
