The Hilton reservationists on the phone never heard of it either. But we just stayed at the Airport Hilton and the shuttle stops at the apart hotel first. It certainly LOOKS like a Hilton. It is the first time I have ever seen a "managed by Hilton" hotel that is not Hilton. I see at least one of the new resorts on its way is also "managed by Hilton." It sure is cheaper and I would have stayed in a minute had it given points. From my recent experiences (so-called rate guarantee, dropped Senior HHonors, etc) I would say it can only get better with Blackstone.
