We have stayed at all 4, we love them all for different reasons, that said if I had to rank them for us here is the order
We just returned from our 4th stay at CSA and it was as good as it gets. We stayed at CTI in November and we are hoping to return to CTI this November. I love the rooms at CSA, and have stayed in the GVS and Garden room, really liked not having a tv! The grounds are also very nice and plenty of food choices. My new favorite thing was having snow cones delivered right to your beach chair with a pour of Appleton rum over it---that was too much fun!
We had the pleasure of having visited all four resorts over a nine day period, despite never having previously stepped foot on Jamaica. This I feel gives us a unique perspective on evaluating the four properties.
So I can say without any reservations whatsoever our favorites in order were:
Altho I'm not sure about liking #3 better than #4 tho.
Reading is fundamental. It's just that for some, it's more mental than fun.
