Congrats and welcome!
One of the locations we thought of while looking was Jamaica as well. My travel agent recommended the Riu resorts, but she suggested the one in Montego Bay. She recommedned the Riu Palace Tropical Bay over the Montego Bay resort.
Here is what she wrote to me: I had a client insist on going to the Riu Montego Bay resort (they are retired, travel often and have already been to the Riu Palace Tropical Bay in Negril). After their return of 10 nights, they said they enjoyed their stay, but…. the food was just okay and became redundant. Also, the seaweeds in the water was a bit unusual and not very appealing for a beachfront resort. That same couple just returned from the Iberostar Montego Bay and loved everything about it. Comparing it to the Riu Montego Bay, they said it offered much better food and service. They also said the Iberostar was the quality of the Riu Palace Tropical Bay in Negril. I have been to all of these resorts, however only stayed at the Riu Palace Tropical Bay.
Hope that helps!
