I didn't think the OP was out of line by posting the thoughts/comments here. It's not like he started screaming at a clerk, waving his Plat card in the air...

I have "high floor" in my profile. I don't think it's an out-of-line expectation for Plats to be assigned high floors in big-city hotels, especially if it's their preference. I think all Marriott Plats have grown accustomed to not getting suite upgrades or even being on the same floor with the lounge. But if it feels like we were either (a) assigned an outright bad room (e.g., one next to the elevator) or (b) given one that completely didn't align with our preferences, I think we have every right to (politely) bring that to the attention of the hotel.

I look at it as a trade-off: in my experience, Marriott is the least likely (vs. HH and SPG) to give me a "real" upgrade (at least a junior suite of some sorts) but the also the least likely to stiff me with a low floor, bad view, wrong bed type, or a smoking room.

Therefore, when Marriott doesn't get that basic part right, I think people have a right to say something.
