3 night run director here...I didn't interfere with results. In an audience of about 600, we sent maybe 15 kids out to count, and my student stage manager tallied those results. While one character (Rosa Bud) got voted in each of the three nights, nothing else was the same.
Individual ballots would take too long to count and using cell phones were ruin the old timey feel.
I do remember having a workshop with someone that was involved with the last revival of Drood just a few months after we had produced it. He asked how many endings we allowed the audience to vote on and was shocked when the kids told him all of them.
If we're not having fun, then why are we doing it?
