So I am a PC Platinum (by virtue of credit card) and would be Gold just through stays I had last year. I've stayed at ~8 properties this year, from Crowne Plaza to Holiday Inn/Express in places from Nashville to St. Petersburg Russia and have not had a single upgrade, even when the hotel did not appear to be very busy. Last year, while still a Gold, I got a few upgrades at different places. I don't care about the upgrade much, I like PC for the ability to get the points and the vast number of properties, but it is starting to feel like there is another set of criteria that I am not aware of by which the upgrade gets decided. Anyone has similar experiences or thoughts?
