Where is the pageant stage?

I had gotten stuck on this as as well and finally got the stage a few days ago. Only because I read through all the steps in elleguseman’s post. Thanks for posting that help! In my situation I had to make Lisa setup fair booths and tap on the fair booths and that was all I was missing. It did require a search through the above mentioned characters jobs. It was then I found the uncompleted Lisa task.
