Monte Carlo on Coventry. I’ve used it many times - you reserve with your CC and pay cash. They also have Day rooms (call ahead, no reservation needed) - checkin with your CC, pay cash when you checkout. Usually about $70 checkout by 4:30. Nothing special, but it’s clean, discreet, lots of parking - there are even side entrances which are unlocked during the day so your guest doesn’t have to go by the front desk.
