"School of Rock" was surprisingly fun when I saw it on my trip last year (it was a last minute replacement show for my sister and I after "American Psycho" abruptly closed before our vacation). However, the audience was definitely the worst out of all the shows we went to see, but that may be because there were more kids in the audience.
I would suggest "Come From Away" though! We saw it twice in Seattle during its run there (we would have loved to have seen it more, but tickets sold out quickly), and it really reaffirmed our faith in the goodness of humanity in times of darkness.
im also planning on getting to NYC at the end of March. Would love to see "Dear Evan Hanson", but it looks like it's mostly sold out until the end of April now. And my sister and I don't really want to waste time waiting in lines for standing room or cancellation tickets. I guess we can try the digital lottery they have, but we usually have our show schedule booked down to a T, so we might just have to wait for the inevitable tour to come to Seattle.
Xanadu! Can't cry on cue!
