How old is she? It's held at Disney World so depending on her age that may overshadow Worlds once you get there. If your current gym is going you can sometimes buy into their packages or you can book yourself on the Disney website for that weekend. There are on property shuttles that can take you to the WWOS, the park hoppers I think get you in for everything but the large senior finals (all girl and coed). There is a thread in the All Star section titled "Worlds 2017 packet". That would be a good place to start.
