Very tough. I loved Finding Neverland and I would tell everyone to see it, but I'm not sure what to take off your list.
Personally didn't love Fun Home as much as some of the others shows I saw this season but many people will argue with me on that one.
I liked The Visit, but probably Finding Neverland more... on the other hand, Neverland will run longer than The Visit I'm sure, and it will also tour, so it might just come near you in the future, too! I liked Matthew and the rest of the cast, but this show isn't carried by it's actors and I can see it being just as enjoyable with a tour or replacement cast.
I'm not interested in Hand To God, but since it's on your list you probably *want* to see it and should keep it.
Definitely keep On The 20th Century, especially if you want to see Kristin perform. This is her show and besides being partial because I love her I also love this show, even after having seen in numerous times. It's just great fun, beautiful to look at and has music I can't get out of my head.
You could think about leaving off King And I for now as this show will likely run into the winter as well, but I don't know how long Kelli will be in and how important seeing her in it is to you. Something Rotten probably won't go anywhere either in the next few months, so I guess that also depends on how badly you want to see it how and with this (great) cast.
I would probably just leave your list as it is and hope you'll be able to see Finding Neverland on your next trip or on tour!
