I hosted a meeting here, and the service was amazing. My attendees said that the guest rooms were very nice, too.
Charlotte hotels are VERY expensive, especially for the fact that there is nothing in Charlotte. They gave me a good rate, provided the size of my group.
The restaurant was OK; they started using those gross powdered eggs in the breakfast buffet, so I'd avoid it. Also, the bar is EXTREMELY expensive. Three of us had two drinks each, and it came out to $80.00. WTF?!
It's in a less-than-nice area, but the Crowne Plaza is an oasis; you will be safe and comfortable.
