What did you think of Cuba?

You've probably got the three most important ingredients for a great time in Havana (Spanish, salsa and a love of music). At 16 though I'd certainly take some company along as the men in Havana might give you a little more attention than is comfortable (and it will halve your accommodation costs). Havana is a good choice as there is plenty to see and do. The only reasons I wouldn't recommend it is if your budget was less than $70USD per day. The food could be a bit hit and miss though probably the main criticism would not be the price or quality, just the lack of variety.
