Took my in-laws, step-daughter and husband. Was really irked about the prices, felt that we could have done something better for that amount of money. Will one one child in our group we were done in about an hour, but had purchased tickets for the cosmic coasters show at the planetarium. So we went to the Lab Cafe and spent $10 on a sandwich and soda. I think that we would have had more fun if all the "cool" stuff wasn't extra. If you want to do all this be prepared to spend an extra $40 and that is with out getting anything to eat.
