The sky is falling
I've stayed at the Marriott Quorum several times over the years and it's always been a good experience. However, times have changed. My wife and I stayed here for 3 nights September 21-24. As a Platinum member, we were given a room on the concierge level. Check in went great. Problems started the next morning when we noticed that the shower curtain liner had a strange stain that looked like blood. I called the front desk before we left for the day and requested that it be changed as well as extra towels. I also left a note and few dollars for housekeeping to remind them as well. Upon our arrival late in the evening, we found that neither request was honored, yet the tip was accepted. We called the front desk and someone finally came at 9 pm and changed the liner and brought towels. On Sunday we went to the Cowboys game and arrived late in the afternoon to find that our room wasn't even cleaned! I went down to the front desk to request that our room be cleaned. I was using a free night on Sunday evening and the manager was nice enough to credit my points back. However, I dont think I would stay here again, even if it was free. We also noticed some very large cracks in the ceiling above the windows that we hadn't noticed earlier. It looked like a chunk of drywall was going to fall on our heads. 
Not all was bad - breakfast in the restaurant was very good; and Angie (our server) was a sweetheart. This hotel is in a great location, so its very sad to see it managed so poorly. Hopefully, Marriott can put someone in place to turn things around.
