+1 on the Super 8. However, it's not really a party place. If you're looking for value and recovery sleep, then it's good. If you want to party all night, then not so good.
I did Best Western @ the Peachtrees last year. Way too far for a walk, but real close to the mall and MARTA. Really really nice place. Just expect to have to catch a cab after the show. This year its about 100 bucks a night, including taxes.
