Yes, although even for cash reservations where you see the room change, that's no guarantee that the property has in fact blocked the suite - as I learned the hard way last week. To their credit, Hyatt customer care did eventually work out a solution with a suite at a comparable nearby property, but only after >1hr on the phone and another hour of waiting, all after I arrived at the property at 9:30pm.

ETA: to address another point made upthread, I 100% agree that this isn't unique to Hyatt and in fact Marriott SNAs are significantly less reliable than GSUs in terms of actually getting the room blocked off, despite being confirmed closer-in when you'd think there would be more clarity about exactly who is in what room.
