Party of 6, with 4 kids between 5 and 19. Good time had by all but not a ton of main exhibit pieces. However what they do have is quite interactive and educational. Staff are all friendly and knowledgable. Prices are generally reasonable but the add-ons can add up quickly. Of the add-ons, I'd suggest passing on the nature tram ride. It's relaxing and has an interesting pre-recorded audio, but ultimately its 45 minutes of driving through a cart path and looking at trees. The bus trip to NASA test facilities was really interesting for the older ones. Overall if you do all of the add ons, its a full day trip. If you stick to the main exhibits its a couple hours max.
