Thanks for the tips guys and gals!!
We are now officially off to St. Lucia!

Booked at the Regency, which according to my Travel Agent is a step above the Grande for a special price! I hope to have a new camera by then, and I hope to get some amazing sunset (doubt I'll be awake to see any sunrises, but we'll see).
What kind of stuff shoudl I plan on stocking uup on while not paying duty? Can I get Cuban cigars there? Alcohol? Jewlery?
