Normally $12 for adults and $8 for children ages 3-18. A family of 4 can save $30 by showing their military ID!
Located on Oxford St. near Harvard Yard, this is a very "classy" museum. This visit inspired my military discount posting - I was just so happy we got in for free. I even took the effort of going to the library to get the discount museum passes (which would have made it $4 per person). Although the husband and I enjoyed the museum, the children (ages 5 & 6) were not too amused. They liked it, but got "bored" easily. Most of the museum is "Do Not Touch" - so it's really not meant for kids under 10 (boys especially) - even though they would never say it. It is cool though.
