all inclusive carribean vacations

Believe or not, the best vacations I had in my life were on places recommended to me on yahoo answers.. one to puerto ricco the other one In Cancun …
this time it is a honey moon vacation in August… I like where I went but it is nice to try new places… a resort with beach. is what we are looking for… all inclusive is nice.. but where in August .. not to hot… ??? debating south America or Carribean… NOT BAHAMAS.. went 3 times and had ver terrible services in different places there…. if you know a place please tell me about specific resorts that you know that have excellent service reputation
