I stayed 2 weeks ago at the Sheraton on the Falls hotel. I had an emailed SNA confirmation, but at check-in was told "as a Platinum member, we upgraded you to a room with a view." I told him it was supposed to be a suite, and he said no. I showed him my confirmation email, he looked at his screen again, and said - "oh yes, it IS a suite." I didn't feel like arguing so I just went to my (regular) room. After my stay, I filled out the survey - don't know that I have ever provided a negative survey before - and the Assistant GM wrote back to say the SNA should not have been removed from my account. I wrote back to say it was. He said he'd try to fix it.
At this point I just don't care about it. I hate having to fight for these things. When Hyatt confirms a suite, I get the suite.
Related, I'll update the review for that Sheraton also. It was not a good stay overall.
