I have spent some time in the islands, mon. It be irie, lol. You drink rum or the local beer, which is always better than American beer. They dance all the time, to "whine" is to grind your hips dancing. Always end a conversation with "ok." The men talk a lot of ****, but are not really that violent. Beggars will get aggressive, but be an Alpha male and they will look for easier prey. Everyone smokes pot. You will probably be ok buying and smoking it, unless you are in Mexico, which loves its corrupt sting ops. Do not under any circumstances try to smuggle weed back into to the US. Buy your own snorkel gear before you go. Kickboards are great if you don't swim well. Sneak a bottle onto the cruise ship to save $. Don't wear shiny jewelry or brightly contrasted swimwear in the ocean - it attracts sharks and barracuda. And wear a condom when you hook up, people are promiscuous and stds are rampant.
