I don't know if this has been discussed but I have a serious concern with upgrades. I hope this makes some sense: I'm very certain that the room type I ask my host for has a certain dollar value attached to it. Before my play can be applied to other comps, I have to first 'play off' my room and other promos. So why everyone else is always trying to score suite upgrades I'm wondering if these work against me. If I'm not with my gf or large group, I'm ok not having a suite and usually ask for a king room. If I get upgraded at check in, which happens, do I now how to play off the price of the upgraded room or the original room booked by my host?
