Great exhibit that 3 of us went to see on Saturday afternoon. $31 admission plus $6 audio tour (be sure to listen to the recordings for kids, too, as they're kinda fun) plus tax made this a $40 visit per person, but it was worth it. All 3 of us loved it. Took us about 3 hours to get through all 11 or 12 rooms.
A few cons=needs more places to sit; photography not allowed; go to the bathroom *before* you enter the exhibit
