Museum Members receive unlimited free admission to the Children's Museum all year long!  Members receive all sorts of benefits: from discounts to special members-only events.  And, a Family Membership pays off in just three visits!
The best thing to do (especially if you have never visited the Museum) is to check out all exhibits and programming offered on the day of your visit. If at the end of your visit you have enjoyed your time at the Museum and would like to purchase a membership, whatever admission paid that same day will be applied to the total cost of the membership.
