If you visit the Museum and LOVE it (we know you will!), you can apply all or a portion of your admission toward your membership. Just be sure to upgrade to a membership on the day of your visit to take advantage of this great deal. 




Ticket Reservations: How should I use/reserve tickets for guests associated with my membership?

Family Plus and Contributing members can still bring guests to Port Discovery at a discounted rate, but you must purchase guest tickets when making your ticket reservations. Admission for visitors and members is by reservation/advance tickets only. Capacity is extremely limited so tickets cannot be purchased on-site. To purchase or reserve your tickets, visit and choose the specific date that you'd like to visit. Your tickets will be delivered electronically and will be valid for the date you selected only.

Ticket Reservations: How do I register for my member account so that I can reserve tickets?

If this is your first time reserving online tickets, you will need to have your membership number to register your account. Review this How-To Guide for instructions. For assistance, email or call 410-864-2665.

Simply visit and use your membership information to log in to your account. Reserve the tickets needed for your visit for all members of your party, including any children under the age of one.

Ticket Reservations: I was unable to reserve a ticket as a member/tickets were unavailable. Why is that?

We're very sorry for the inconvenience and appreciate your understanding. To ensure that there's plenty of room for play, learning, and safe physical distancing, we've significantly reduced the number of tickets for each day. This means that you'll enjoy the Museum experience with fewer people, but that tickets may not always be available for the day you'd like to visit. At Port Discovery we continue to thrive as a non-profit organization that serves our community – so tickets are reduced total capacity to that more families can enjoy the Museum.


Museum Membership: 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. You can also become a member by calling 410.864.2665.

Museum Membership: 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.

Museum Membership: 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. General admission tickets can only be applied towards a membership on date of visit only.

Museum Membership: 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.

Museum Membership: 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 120 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.

Museum Membership: 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 and a valid photo I.D. 

Museum Membership" Does my Membership start immediately or by calendar year?

Your membership will begin on the date of purchase and will expire at the end of the month the following year. Example: A Membership purchased on 7/1/22 will begin on the date of purchase and expire 7/31/23.

Museum Membership: 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 5 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!

Museum Membership: How many Membership cards do I receive?

One membership card is issued (emailed) per membership.

Museum 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.

Museum Membership: Can my Membership Be Used to Pay for Group or Birthday Party Visits?

We're sorry, but memberships are not applicable for Port Discovery Birthday Party packages/admission or for group visits.  Port Discovery offers special activities and programming exclusive to both birthday parties and school/camp groups, and these activities are not included as part of our general museum membership admission.
