If you're up for a good hike (challenging)the views from the volcano are fantastic and would be worth spending a couple days on the island for, but as suggested Bequia is a great little palce and you can take a day trip to the Tobago Cays which are amazing.
Air Canada is flying direct to the ne airport so traveling there just got a lot easier.

Drink all day at home, your friends worry about you; do it on vacation and they say "what a good time you're having". Save your friends needless worry, travel more!
