Most places won't take 2 year olds becuase they are not ready to deal with that kind of structured lesson where they have to do just what they teacher is trying to teach. Let her keep dancing at home, and keep music going for her to move to.
You can check the local community education programs, usually through a school district, for classes geared toward very young kids. It should be something very loosely structured, where they give ideas and maybe "props" (ribbons, etc) and the kids can move & dance how the music makes them feel. She'll probably be much happier in something like this than a structured "do it exactly how I told you" kind of environment.
