Had a "meh" stay at Radisson Nashville Airport last week and just filled out the standard survey with the concerns we had (some recessed/accent lighting not working, mildew smell, couple other things). The manager replied back roughly two hours after I submitted the survey. He apologized for the issuses and offered me a courtesy night in the future. Is this part of Carlson's plan to win customers from the other reward/elite groups? If so, I'm impressed. Perhaps this is just an isolated incident, but it's a definite positive for a manager to be this pro-active with concerns being raised, especially when I wasn't really complaining about the experience - just offering my opinion on the experience with what was good and bad.
