As the title suggests, I'm looking for a Hilton property for a 5-night anniversary stay in mid-October (this year - I know, late planning).

Airfare should be reasonable for most locations, I'm thinking along the lines of St Thomas, Turks & Caicos, Anguila. Could even be Key West.
Would like relaxing beach but also some stuff to do ( not really shopping, casinos, clubbing)

I'm hoping for an award stay at/below 120k/night (5th night free for Diamond) and bonus for great Diamond treatment, lounge, breakfast, etc.

Anyone have favorite properties?
