Here's a photo from the press that has started to come out after the conference wrapped up it's initial debut, but I don't think it's anything wildly new except that Hyatt is supposed to have 1000+ properties work with Apple Wallet, and I doubt they have close to that many right now?
P.S. Sucks for whomever checked in, I don't know this property but I imagine this is a second floor room which who would want that? (I am sure somebody but...)
