The priceline topic below got me thinking.  It might not work for just one date, but how about if a hobbyist was looking or a week-end date.

All expenses paid, long week-end (leave Friday come back Monday ) to a wonderful resort in St Barts, in the middle of a frigid February.

Thats airfare, transfers, dining and dancing, long strolls on the beach, maybe some shopping too.

Now that might start a bidding war. Subject to a compatibility test date.
