I guess this is normal, but its never happened to me. Yesterday I took advantage of a few comp nights at the Golden Gate. They asked for my credit card to hold $100. I assumed if that was just a deposit but she said they would evaluate my play at the end of my stay to rebate the $100.
I may be wrong, but it sounds like they hold the money and if I dont play/lose at least $100 then they keep it to cover the room. Im not worried about it, because I easily play/lose more than that, but it just seemed odd.
