I''ll be in Atlanta a lot this summer and can get same rate at available Marriott affiliated properties downtown. For most of my trips, it's a choice between the Marquis and the Ritz. As a Platinum Premier with a MR credit card, should I stay at the Ritz Carlton or the Marriott Marquis, considering points, treatment, possibility of upgrade, etc. They are very close to each other so location seems moot. Any advice?
