<p>When my son and I visited Ithaca, ( not for theater, but the Park School,) we wandered around the school , bumped into a professor, who talked shop with my son and invited us to a class of his later that day where student’s films were going to be shown. It was a great coincidence, but we helped create it… Be friendly, call before and see if they will help accommodate your situation. Theater schools seem to have strict rules about outsiders sitting in on classes, understandable. I can’t think of a question to ask or not ask, cept to be natural, inquisitive and see what comes up. The one school my daughter did not get to see the Theater School , she did not end up applying to. It is really important to get a feel. meet students, smell the halls, see the bulletin boards, and how the school treats your specific request. It all adds up to how you experience a place. The more info you gather the easier it is to assess the school realistically. The schools want to know all about you, and you want to know all about them. Then there can be a good fit. Good luck.</p>
