As a follow-up to my question:

The hotel check-in agent couldn't have been nicer.

He attached my Diamond number to the reservation and said that he would try to find me an upgraded room. I told him not to worry about it, as I wanted to unpack and rest. He looked around for a moment and was able to find me a renovated Executive room.

He gave me the internet code and programmed my key for the Executive Lounge.

He thanked me for my loyalty numerous times.

A great stay.
