It was terrible!
From checking - rude staff. Several people at our conference had bed bugs in their room; others entered dirty rooms; some others had strangers trying to access their rooms after rooms were double booked.
I had no trash cans in my room.
To make matters worse, a grease fire in the kitchen on the top floor was initially dismissed by staff as regular cooking smells. When the building was evacuated, some of the stairwells and passageways were difficult to pass through and in one case, the fire exit door was locked. The fire marshal needs to go and check out the building and I am horrendously disappointed with Marriott where I stay on a frequent basis perhaps no more.
