I really really want to take a vacation here. Whats a good tourist spot?
depends on what you want to be honest. If you want the nature vacation, it's going to be in the South, mainly Soufriere, but those are expensive "hideaway" spots and mainly the honeymooners/ rich and famous go there.
The North is where the action is pretty much, but I would stay away from the Sandals style all inclusive hotels. It might be cheaper initially, but I've talked to tourists who complain that they tend to restrict your movements by tailoring what THEY think you'll enjoy during your stay.
Anyway, must do events, Friday Night street jam in the North. Go to the Soufriere Volcano and take a bath in the sulphur springs, any nature trip or climb the pitons(see below) if you're the adventurous type.
Would probably recommend coming during the Jazz Festival, normally around May. Get some fairly high profile acts for small money. Not peak tourist season, so should also get some good hotel/flight rates.
Carnival is July if that's your thing.
