I am staying at Flamingo 5 nights for free besides the fees. Staying in a Fab Room right now but when I called they said they put me down for an upgrade possibility. If I eat at restaurants on CET properties I understand I can charge to room and have to the possibility of getting some of the meals comped at checkout. However, since my rooms are free, do I need to play enough to cover the free rooms before I can get into getting my meals comped? Is there any other benefit of being able to charge meal to room besides possibility of getting comped?
