I hope that you have a blast, Baraka_Guru. As a Floridian living in a Communist country (but have never been to Cuba) , here are a few thoughts:
- Consider travel insurance/ buy with your credit card. Hurricane parties are terrific, but suffering one at a hotel having your trip canceled is a bummer.
- Drink lots of bottled water. The sun will make you tired. You're going in the summer, so discard this idea of pleasant warmth -- HOT, HUMID DEATH HEAT. Drinks will umbrellas also get you accustomed to this.

I'm not sure if
Cuba Libres are on the menu or not, but they are delicious.
- Can you swim?
- Sunscreen thoroughly. That little line above your swimsuit that you missed? Yeah, that's going to be fire engine red and that's going to hurt when you go to sleep. Be through. It's liquid salvation from burning.
Let us know how it goes!
