How do I become a member?

A membership at Port Discovery Children’s Museum offers a full year of imaginative and purposeful play for your entire family! Enjoy unlimited admission and exclusive benefits like free member-only events, sneak peeks at new exhibits, discounts on birthday parties, and much more!

Enroll online via our Museum Membership webpage  or sign up at the Port Discovery Box Office during your next visit and receive your membership on the spot. (Please note that memberships cannot be purchased in the Members Express line.) You can also become a member by calling 410.864.2665.

How often can I visit as a Member?

Membership to Port Discovery allows you and your family unlimited visits to the museum for an entire year during our normal operating hours.

If I am not a member, can I apply the cost of general admission towards a Membership?

Yes, but please read on for details!  Many new guests like to "try" the Museum before purchasing a membership. The purchase of general admission can be applied toward membership only on the day of purchase and only on a one-to-one exchange. Only tickets from one receipt/transaction can be applied to a membership. For example, if a visitor purchases five (5) tickets to the Museum and then would like to apply the purchase to the Family membership only the cost of four (4) tickets may be applied. 

How much does it cost to upgrade an existing Membership, and does my expiration date change?

The cost of an upgrade is:

  • $30 when upgrading from a Family to Family Plus (6 Person)
  • $50 when upgrading from the Family Plus to a Contributing Family
  • $80 when upgrading from the Family to a Contributing Family

Your membership expiration date remains the same upon upgrading to another membership level.

Upgrades cannot be applied to memberships purchased through Certifikid or third parties due to ACM restrictions.

What is an ACM reciprocal membership?

A reciprocal membership with the Association of Children’s Museums (available with the Family Plus/Contributing Family levels) allows you to visit 200 other participating children’s museums around the country for 50% off general admission for 6 people. For a list of ACM museums, please click here. Each museum has a unique admission policy. Please contact the museum you will be visiting to find out more information.

Port Discovery welcomes ACM members every day the Museum is open to the public.

Visiting members must provide proof of a current reciprocal membership to gain entry.

One adult named on the card must be present at the time of entry. Up to five additional guests may accompany the adult cardholder into the Museum.

Can I loan my membership card to my mother, father, sister, brother, nanny, etc.?

Our members can send their children to the Museum with a temporary authorized person (e.g. nanny, grandparent) with a signed note to use their membership at no additional charge. For safety reasons, your guests may not be admitted without a signed, dated note with contact information.

Does my Membership start immediately or by calendar year?

Membership starts on the date of purchase and will expire the following year at the end of the month of purchase. Example: A Membership purchased on 7/16/19 will begin on the date of purchase and expire 7/31/20.

When does my Membership arrive?

Port Discovery has gone green! Your card will be sent via email to the email address listed on the membership within 3 business days. Should you wish to visit the museum before receiving your card via email, bring your photo ID and the Box Office will welcome you for a great visit!

How many Membership cards do I receive?

One membership card is issued (emailed) per membership.

What should I do if I lose my Membership card?

In case of a misplaced membership card, contact the Membership Department at 410.864.2665.

Do you offer a Corporate Membership Program?

Yes, Port Discovery welcomes corporate members! We offer several different levels of corporate memberships. Please visit our Corporate Memberships page for more information.
