This was for a community theater (NJ) - so a tad different than a school. But was associated with our Education Department. The parents, except for one, all understood the show and knew what ot expect from it. There was only one parent who was not happy with the two times her daughter had to kiss. So my advise would be to make sure parents know your direction ahead of time. We had about 20 kids in the show - again, this was a 24 hour musical so they only had 1 day to prepare and perform the show, but the quality was that of a full 6 week rehearsal period.
