YMMV. This is probably the elite benefit I have been denied most often since it became a Platinum/Titanium "guarantee". Even when granted it is usually accompanied by a room downgrade (as others have pointed out) or some other condition. Just recently I was denied a noon checkout (vs. 11 am) due to "government regulations" regarding Covid room cleaning requirements - a totally made-up excuse. I'll be testing it again at the Toronto Airport Marriott in the next few months, with low expectations.
