stayed at Excalibur 6/25-6/28, all cash nights, stay posted on July 3rd. Stayed at Aria 6/25-7/1 (4 nights free + 1 cash), and nothing has yet posted. Host tried to comp my 5th Aria night but I told her no, I need it for Hyatt credit. She then thought I was asking for more comps in lieu of the hotel night and said this is not a negotiation, but left the 5th night on. I've never had a problem with stays auto posting in the past, hope this isn't an issue.
