How was your experience?
If you are going for a museum experience (i.e., displays, readings, recordings), it's wonderful! If you are going for a "spy" experience, beware it costs extra. While you have to choose a secret identity before entering the museum's permanent exhibit, you do not interactively use it during your time in the museum. There is a computer at the end where you test your memory skills about your undercover identity. Unfortunately, children must be at least 12 to take part in the spy experience - it would be nice to have something for the younger crowd, too. While my kids (9 and almost 11) enjoyed the hands-on parts of the exhibit, they did not feel like they had a true spy experience.
