IMHO, the C/D lounge @ CLT is one of the best US Airways lounges and I've been spending quite a significant amount of time in it since the beginning of this year. I would typically head straight to the 'Quiet Room' as to avoid the rowdiness of the outside! . Yes, I am in it currently! The Room is comfortable and quiet, sure, you may be able to take a nap, but the seats are of vertical nature as opposed to slanted or full-flat! You may also want to regularly check the front desk for your flight status! There would be no roasted vegetable soup for you, since it would typically only vailable late in the afternoons.

As far as I know, the B concourse's lounge has the same type of snacks etc. but it tend to get quite crowd.
