Hello Leader of the Club. You could possibly qualify for an AP rate of $49.00 plus tax if there are any rooms left. They only allow a certain amount of rooms at this rate. Can't remember for sure, but I think I read an earlier post that said the AP rates were not available for the first couple of days of their opening (they don't open until December 14).
Just wanted to report that I got the $49 rate at Pop Century from Dec 16-20th. I asked for the Annual Passholder rate. When I received my confirmation in the mail it has code AMI on it.
