Ok dear husband, you are right, the "Cosmic Collisions" planetarium show is NOT for 3 year olds. She'll recover. And they were nice and refunded our tickets. "To Fly" was completely overbooked by the time we got there. Even though we went early enough that there weren't any lines (11:15 on a weekday). She loved Viking space capsule. And the airplane wing, with the enormous planes soaring overhead. She agreed that we could put the space claw back on the rack in the shop until her birthday.
