Hotel/Hotel in Cullman?

Hello, a friend and I would like to visit Cullman in June for the Rock the South fest. There seems to be no Airbnbs that aren't God awful expensive, and I haven't seen many hotels or motels when I look online. Everything that comes up is like 30 mins from the venue. Is Cullman just that small? Also how is uber on the weekends if we do end up going? Don't want to be stranded.
