If there is an adult outside the primary (or secondary, for 2 adult + 4 child memberships) cardholder who may be bringing your family to Discovery*, you may want to purchase a membership card for that person. Examples may include grandparents, older siblings, child care professionals, etc.
*Note: Additional adults do not add to the total number of adults covered by your membership; rather, they allow another adult access to your membership tier. The adult you added can take your guests to the museum, in place of you. For example, a 1 adult + 4 children membership could add a guest to be eligible to have ONE OF TWO adults able to use the card, but not both at the same time. Only 1 adult per visit will be admitted using the membership, and any additional adults must pay regular admission at entry. (For a 2 adult + 4 children membership, TWO OF THREE adults would be able to use the card, but not three at the same time. Only 2 adults per visit will be admitted using the membership, and any additional adults must pay regular admission at entry.)
