Crowne Plaza International Just lost my business, not just the Charlotte location
I previously had an expectation of quality for Crowne Plaza, so when this group stepped up and provided rooms for a group of my travelers..I was pleased and booked with them immediately in a show of loyalty.
Unfortunately, the facility itself and maintenance was lacking. My room needed a light bulb to be placed in the lamp (not even one in the lamp) the standing lamp didn't work at all, the carpet joining location in the bathroom had staples/teeth extending from the strip. In the hallway, the carpet had raised area right down the center that was unsafe. When in the elevator, it jumped from the lobby to the banquet level and then stopped, didn't open the doors, then finally moved on to the 9th floor.
If you are even a deep sleeper, good luck here. The walls are paper thin. I am a deep sleeper and was awoken by people next door just visiting on their beds near the wall. During the "awake" time, I heard them also so it wasn't a situation of late night loud drunkards or anything.
The business center had office 2003 as it's software (not even 2007) and had so many errors in loading the software so I could open my document, I finally had to leave before I became more upset. 
The front desk employees were very kind, and the Bar and their staff/food was very good.
Not only will I choose not to stay at the Crowne Plaza in Charlotte, but when I have a choice in the future; I WILL NOT choose Crowne Plaza anywhere.
