I was upgraded earlier this year to a king bed room and I agree that most upgrades are unintentional & simply a happy, random by-product of last minute room re-assignments. I didn't ask for the upgrade & also didn't have a particularly friendly or pleasant CM at check-in. I checked-in early and my room wasn't available at that time. When I asked if any room was available, she advised "no, but you're getting a king bed so that's good enough." It was the busy President's Day weekend so I believe they wanted my standard 2 double bed room for a family. The king bed mobility-assist room was unoccupied & so that is what I received. I was happy to get the king bed and the bathroom was larger so a good situation all-round for me.
