I was there about two weeks ago. As diamond on a paid stay I was given the choice of an upgrade, a $32 (Or something like that) credit for breakfast one morning, or 1000 HH points. I went for the breakfast and the check in person told me they gave me the upgrade anyway.

I got a room in one of the villas and it was nice, but I wouldn't call it an upgrade at a luxury hotel. It felt like a mid class Hilton from the 80s, but certainly nothing wrong with it.
