I thoroughly enjoyed it, but my wife could not wait to get out. I thought that it was extremely interesting, and learned alot. It is very extensive, and they claim it is the world's largest dedicated to computing. You can take a tour if you like, but we tried it and then broke off to go by ourselves so we could go at our own pace. If you are interested in computers and math, you will absolutely love it.
Admission was $15 each, seniors/students/military is $12, and children under 12 are free.
