That is what happened to me after signing up for the slot card at Harrahs E Chicago. Since then I have spent 15 nites comlpiments of Harrahs and hope to get one more invite if they ever reopen the New Orleans property since we were supposed to be there shortly after the hurricane hit. I have been staying at Circus (and other Mandalay properties) for 30 years and have never had a free offer from them. Go figure.
