My daughter did in back in May, on Memorial Day weekend. We had a PPO ADR at H&V and they let us sign up before eating. We did the last show of the day because she wanted the sabers to be lit up. All the shows were open at that time and no line. When it came time for her show several children didn't even show up and the CMs were trying to recruit siblings of the ones who were there and trying to talk people walking by into joining in. They ended up going on stage without a full set of kids, so I highly suggest checking 10-15 minutes before show time to see if they have spots they need to fill if you are unable to get in at the start of the day.
