I recommend the downtown Hilton. Walking distance to 6th St. area for after parties; and the shuttle usually comes within l blk. of it. Reserve now and you'll get a decent rate. Best concierge in America: Tarik Carter. Great pool and health club where you're sure to hang with some bands...within two miles of venue for ACL (can't remember the name of the park, but I think it's Rilker...).
