I was in Charlotte during a NASCAR race weekend. Although I wasn't attending the races, hotels were pretty full and many at the Comfort Suites were obviously race fans (apparel, logos on vehicles, etc.). There were many families with children but I did not hear any disturbances at night.
The free breakfast buffet was adequate (not anything to rave about). The room was clean, bedding in good condition, refrigerator working well, etc. I was impressed by the desk clerks and the way one handled a problem with a customer. They were also quick to offer maps and directions to those unfamiliar with the area. The clerks were both friendly and competent--a good combination. I also liked the location, near Interstate 85 exit and just off Billy Graham Parkway but still not noisy traffic. As I said when checking out, I will probably stay there again.
