I don't have a playbill, but if you there is one, surely someone here will have it. It would be wonderful if you sent a note or card to the cast of the shows that you enjoyed so much. Something like that would mean the world to those actors. I was a performer at Club Med about 11 years ago (yipes) and I still think about this one family in particular who wrote to us. I remember the father's name was Robert and the daughter was Christine...it just touched me so much that we had made such an impact on their vacation. And it certainly doesn't hurt to feel validated as a performer.
Sometimes we don't think our words will have much impact on others, but they do. Here's an opportunity to say thank you for making your vacation so memorable!!
Cheers.
