Has anyone been told at the New Orleans Marriott that if they want an UPGRADE to a larger room(suite, etc) that regardless of availability it is never FREE. They tried to charge me 50% of the room value on top of the current rate of a standard room for an upgrade. The most that you get for a FREE upgrade is a room with a better view or concierge floor. My understanding of the rules for upgrade is "Based upon availability at check-in". No charge is mentioned. Am I wrong or how do they get away with it?
