I went to the Hall of Science twice with my four year old before I realized that it was WAAAAY bigger than I had thought. The first two times we went, we went to two small areas, one above the other, with some play stuff and exhibits. Okay, I thought, not bad.
Then the third time we went I bothered to ask someone who worked there, ""Hey, is this it?"" They pointed me in the direction of the central hall which is a HUGE round area on two floors. More ""gadgets, gizmo's and machines that go bing!"" than you can imagine.
MAKE SURE you ask where ALL the exhibits are! :-)
