FWIW, got the same kind of treatment from this property 3 years ago as a silver on an award stay... upgraded to a larger corner room (not lakeview, darn), top shelf liquor, snacks waiting in the room, etc.
I've always wondered if a gold or diamond didn't show up that night though since the letter in the room was addressed to someone else.

Doesn't matter... they impressed me and we had an excellent 4 night stay. Glad to see things haven't changed.
