This is really an opinion question.
I'm planning a family trip to Chicago next summer. I've decided to get Chicago CityPASS's for the whole family.
I wish to explore the Shedd Aquarium, the Adler Planetarium, and the Field Museum (all right next to each other). I really enjoy that kind of stuff, but I don't want to spend three days of our trip in the same area, so I've decided to try to cram two of these into the same day and devote a second day to the third.
So my question is, which of these three takes longer to fully explore, or would be most enjoyable to a serious nerd who loves planets, oceans, dinosaurs AND technology?
