I looked at the app and it showed regular rate of $236 for that Thursday night, 19th)but showed I get comp for Friday night( (20th) plus three days the following week).
The next morning, I'd spent enough on the 18th to hopefully warrant another comp for another night.
However, the night of the 18th was booked at Cherokee due to poker event, but they showed I had a comp on the 18th for Harrah's Valley River casino an hour away, so I confirmed that reservation and stayed there with comp. I spent 4 days at Harrahs Cherokee resort, and spent enough on tables and slots to be rewarded at least one comp night.
