The Children's Museum of New Hampshire has ASTC reciprocal agreements with all local members of the program within 90 miles except for the Boston Children's Museum and Harvard Museum of Natural History. Families with a current ACM (Association of Children's Museums) Membership from another organization can visit the Children's Museum of New Hampshire and receive a 50% discount off up to 6 regular price admissions ($10 per person). This may not be combined with any other offers.
Amber is correct. Present your Boston Children's Museum membership card at the Children's Museum of NH and you can get up to 6 people in for half off.
Not sure I know that there are a number of museum passes you can use so maybe.
