Just came across this and wasn't gonna comment. But.............
I can see where Hilton might want to honor this. My partner and I just returned from one of those Starwood free weekends. Stayed at the Phoenician in PHX. We arrived Late Fri nite, left Sun pm. The room rate was $0.
My final bill with meals, drinks, massages, etc came to $1400.00.
We never would have gone and payed for the room at this time.
Starwood won!
