If you're into Hilton. I recommend the Aspire Card. If you look into it, Free Night (standard night when you search points on website, which can be Waldorf), 14X, some credits, etc.
The KICKER for me is the ROOM UPGRADES. They seem best overseas, but book the cheapest and get the Upgrade. I've haved over $2,000 on some nice rooms.... Oh and 14x pointson many HGVC fees,, sign up bonus, etc.
Worth a look to me.
