I've never repeated a show on Broadway, but I have seen the same show in multiple places around the world; Mamma Mia and Wicked both come to mind.
We just returned from an NYC trip, and got to see three shows while we were (thank goodness for family in town who watched the kids!) Absolutely loved Dear Evan Hansen, one of my favorite ever scores I think, and the whole cast was spectacular. Hello Dolly was a great show, my husband adored it and has raved about it to everyone ever since. I'm obviously in the minority, but I didn't care for The Great Comet, I just couldn't get into the music at all. Everyone else seems to love it, so I would have given it another try, but it's closing before our next trip.
We have tickets for Come From Away for our next trip, trying to decide what else to see. My theatre-loving 4-year old is desperate to go to a show, but I'm not sure what he might like. The Lion King is coming to Orlando, where tickets will be cheaper, so we'll just see it here, and I know some shows have age restrictions. I'd love recommendations if anyone has any. He's already seen Finding Neverland, Wicked, Mamma Mia, and Matilda.
