I just booked a 4 night stay Saturday 30 AUG 08 through Wednesday 03 SEP 08 at the Hilton Waldorf with no problems using Diamond Desk. The other property that was highly recommended was Hilton Trafalgar. Both locations are 40,000 points per night. I ended up going with Waldorf since it's very close to the theater district and it has a nice workout facility including pool and stream room.
I'd love to hear from anyone who has stayed at the Waldorf or Trafalgar to hear personal experiences. My email account is
