The deal runs from January 3 through April 30--which at least gives you time to ask Santa for a five-night stay in a villa.
To put things in perspective here (because our minds are boggling, too), the best available rate for one of the four-bedroom villas is around $4,291 a night. So when you're looking at a folio of over $20K, that $6,000 airfare compensation... still sounds like a deal, but really more of a "deal"--in air quotes.
The villas do sound pretty special--there are both single story and two-level versions and interiors are all designed by Wearstler. Villa guests get priority status at the spa, restaurants, lounges and pool cabanas, and are assigned a dedicated "Lifestyle Assistant" who can take care of special requests and even packing.
Don't expect to see Kel in the villa next door, though. She'll be in Paris.
