Who is included in my Individual Plus membership?

One adult and one guest. Member can bring any one additional guest with them to the Museum. Guest cannot visit the Museum without the named person on the membership. The Individual Plus membership comes with one membership card, 4 guest passes, and reciprocal benefits through the ASTC Travel Passport Program.

Why don’t you give membership cards to children?

We give two cards to the adults per Family/Grandparent membership. Children 17 and under are included in their family’s or grandparents’ memberships. They do not need a separate card.

Who can purchase a senior membership?

Persons who are 62 years of age and above qualify for senior membership. To purchase a dual senior membership, one person must be 62 or older. 

What is a “Guest of” membership card?

For any membership that comes with two cards, we offer a “Guest of” option in the case that a member would like to bring a different guest each time they visit. By selecting the “Guest of” option, the Family, Grandparent, or Dual Senior member only has one permanently named person on their membership. “Guest of” card entitles a member to bring a guest with them but does not allow guests to come without member. Guest passes can be used without the presence of a member.

What’s included with the guest passes?

Members can give their guest passes to friends and family and take advantage of free general admission. Films are not included with the guest passes and cost an additional $5 per person to view all films.

How long does my membership last?

Your membership is good for one year from the time of purchase. Expiration dates fall on the last day of the month.

What is the ASTC Travel Passport Program?

The Nat participates in the Association of Science Technology Centers (ASTC) Travel Passport Program. Members at the Family and Grandparents levels and above are eligible for reciprocal benefits such as free general admission when you travel outside of your local area.

According to the rules established by the ASTC, membership cards are NOT honored at institutions within 90 miles of the institution where the membership was purchased. Cards are also not honored at institutions within 90 miles of the cardholder’s residence. This is not the policy of The Nat, rather it is the policy put in place by the ASTC Travel Passport Program.
