Being a former Columbia Sussex employee (I worked at the Buttes, A Marriott Resort,
www.marriott.com/phxqq) I can say that they treat their employees as poorly as they keep up with their hotels.
That being said, the CP in Knoxville isnt all that great either. Their respect for PC benifits is non existant and their upgrades are the same. I have heard good things about the Hilton, but also heard its hit and miss.
