I stayed at the GSP Marriott on December 17. This was my first time here, so I don't have any point of reference in regarding downgrades at the Concierge Lounge at this property, but the food/drink offerings seemed to be pretty good. A hot dish with usual accompaniments at dinner, plus a nice dessert selection. In the AM there were fresh scrambled eggs along with bacon and sauasge, along with the expected offerings.
If Marriott really wanted to cut down on CL expenses and improve the guest experience for those who were entitled to be there, it would eliminate the freeloading, like the group of seven people who walked in around 8:00 PM for dessert. Although I can't say it definitively, these folks gave me the distinct impression that they had never seen the inside of a CL before this particular night. At a minimum the lounge attendant should ask everyone to sign in, as this might be a way to cull the herd.
