After talking with the front desk at the hotel I'm at now (RI Atlanta Midtown/17th St), Marriott Platinum Reservations, and Marriott Platinum Customer Care, here is the general consensus we came to. It is a glitch in the FOSSE system (I've never worked with this system before so I'm not familiar with it) that tags the reservation as a point upgrade in the MARSHA system (thus showing as such online), however, when the front desk clerks issues the upgrade, FOSSE does NOT indicate to the clerk that the upgrade is costing additional points. In fact, the clerk even agreed today that if the system ever states that additional points will be deducted, they never issue the upgrade. The front desk manager acknowledged that if the additional points do come out of my account then they will contact Marriott Rewards and have them credited back to my account ^. I'll post back and let everyone know what happens...
