I am platinum and do enjoy the benefits and you get extra points for your stays..
There are a lot of specials at this time of the year. The thing is that you will have to check in. If you really didn't want to stay, you could just leave the key in the room. Better find a place that you would enjoy a few nights at.
I apologize that I wasn't able to answer your question any sooner. If you had a 2 night stay, then I assume your stay will post within the next couple of days and you'll be upgraded. If you weren't able to do that, send me a private message with your account number and I'll see what I can have done.
