What to do with my twin 11 YO girls in Chicago tomorrow

I have my twins tomorrow from 10 AM till 4 PM. We were going to go to Navy Pier but it looks like it’s going to rain. I’m thinking perhaps the museum of Science and Industry instead…
Any other suggestions?

Tomorrow is Easter.
What will be open?

Churches.

The museums are open

If you have time for only one, it’s gotta be the Field Museum. And you’re right by the aquarium.

Lincoln Park Zoo. Use umbrellas to get from building to building. But don’t miss the Eugene Field memorial.

If you can convince them to look at art, the Chicago Art Institute is one of my favorite museums in the world.
