Following up to thank everyone for their feedback.
Along with Fun Home, Curious Incident, and Hedwig, we managed to squeeze in both Hand to God and Sleep No More, as well.
Sleep No More was mind-bending. Still trying to take it all in days later, and I've been busy reading up on the details and all the bits I missed. I keep learning more about the scenes I encountered and wishing I could go right back and visit it again. Didn't get any 1-1s, but I did have a semi-personal encounter with the Porter in his office which was great. Also, the show was just right for my husband: no stress issues at all. Loved it!
And Hand to God... wow, that was phenomenal. I've never laughed so much at any show in my life, but it wasn't just a shallow comedy either. I'm replaying the scenes in my head, and I hope I get to catch it again on a future trip. The actors were great all around, but Stephen Boyer gave what is probably my favorite performance ever.
Thanks to everyone who helped me plan this trip.
