I'll admit that I waved to Timothy Hughes from a distance (he was NOT stage-dooring, btw, luckily) after I saw Hadestown in November but for the love of everything, please don't actually try to stage door! It's not worth the risk to yourself or the cast. It's not even allowed at the moment.
If you want a hello, maybe you could hit up Cameo. If you want a signed playbill you might be able to mail one out [edit: with a donation]. I don't think any shows - Broadway, touring, West End, regional, or otherwise - have stage-dooring in place right now, as well they shouldn't! I understand wanting to compliment the cast (and get material things such as selfies or autographs) but please know that, right now, it's not worth it and is frankly stupid and risky."
Second the idea of mailing in a Playbill. I did that for most shows I saw and accompanied it with a lovely card. (Didn’t send a donation unless they asked). I heard back from Chicken & Biscuits, Thoughts of a Colored Man, and Six (which requested a $60 donation).
