We've been to Cuba, Martinique and Cancun. Cuba is beautiful in its own way. The beaches are freaking amazing. But you won't eat well. The food is terrible. Plus, the people there are almost starving so you feel bad eating whatever they offer. Everyone is after your money too. People who want to take you on a tour to visit Havana or any other places have shitmobiles that barely hold together and are a moment away from breaking and having an accident. And don't drink the tap water and don't eat from any outdoors buffet.

Martinique is wonderful. Amazing beaches, amazing food and especially the rum! Lots of great activities to do and places to visit. And you feel safe. I've had a wonderful time there. Truly the best tropical destination so far.

Cancun was great. Went to an all inclusive resort. It's nice but if you stay in the resort you won't experience the true Mexican experience. The food is good, but very "white people" if you get my drift. If you want authenticity you have to go visit Cancun city proper. And you will get charged extra for EVERYTHING. We call it the gringo tax. Everyone will be after your money. And you won't feel safe. But overall it's very cheap and you will eat very well. Just don't drink from the tap.
