Grandparents Membership Frequently Asked Questions

Who is admitted free with my Grandparent membership?

– The grandparent and partner/spouse, named on the membership.
– Each named member grandparent may bring up to four (4) grandchildren under 18 per visit (Maximum: 8, if both members are present).
*Note: Free admission is not valid during blackout dates for fundraising events like Snow Days, or for admission to birthday parties.

Who must be present to receive the member benefits?

At least one of the named members must be present to receive benefits.

Who can use my membership card?

Only the grandparent(s) named on the membership card can use it.

How do I check in with my membership?

For faster museum check-in, download and scan the digital eMembership Card from your smartphone and let the attendant know who is accompanying you to the Museum. You can also present your physical membership card. (ID may be required.) 

Can I share a membership with my friend or other family members?

Memberships are non-transferable and may only be used by the grandparent(s) listed on the membership. The second adult listed on the membership can only be the current partner or spouse of the primary member, who lives in the same home.

What if I bring my 6 grandchildren and one of my adult children? Who do I pay for?

You may bring up to 4 grandchildren for free per member grandparent present. This means up to 8 grandchildren can be brought in for free when both member grandparents are present; general admission is charged for additional children and adults. In this scenario, you would pay for your adult child and the extra 2 grandchildren.

I came to the Museum this weekend and paid general admission. Can I use my receipt as credit towards buying a membership?

Yes, you have 14 days to apply one admission receipt to a membership purchase at the Front Desk.

Do I get free passes with my membership?

– Family: 4 single-use guest passes
– Grandparent: 4 single-use guest passes
– Collaborator: 10 single-use guest passes
– Innovator: 20 single-use guest passes

Can I get a refund on my membership?

As a 501(c)(3) nonprofit organization, our memberships are non-refundable. Thank you for your support and understanding.

Can I transfer my membership to someone else if I move out of the area?

Membership benefits are non-transferable and may not be re-sold. The membership may only be used by the members named at purchase. You can continue to use your ACM reciprocal benefits at participating museums for the remainder of your membership year.

Can I purchase a membership for someone else?

You may purchase a membership for someone else as a gift. You will need to provide their name and contact information at the time of purchase. Memberships cannot be transferred or re-sold.

How long until I receive my membership cards?

CMOSC offers digital membership cards through the eMembership Card app. Cards can generally be downloaded on the purchase date. Click here for eMembership card download instructions. Physical membership cards are only available by request and will be mailed within 1-2 weeks of purchase.

What is the ACM reciprocal network?

ACM stands for the Association of Children’s Museums. We participate in the ACM network, which allows CMOSC members to receive discounted admission at other participating children’s museums across the country (dependent upon the membership level the visitor has). Present your CMOSC physical membership card or eMembership card at any of the 200 reciprocal museums across the country to receive 50% off general admission for up to six people, including the cardholder. For a complete list of ACM Reciprocal museums, click here.

What if I forgot my membership card and I’m visiting another museum that is part of the ACM network?

If you’ve downloaded your digital member card on the eMembership Card app, you will always have proof of CMOSC membership with you while traveling. You may present your digital card with your photo ID at the museum you are visiting. You are also welcome to call our Front Desk during regular business hours (Wednesday through Monday, 9am to 4pm PST; closed Tuesdays) at (707) 546-4069 to verify a current active membership.

Can I bring a guest, who is not a member, during Member Mornings?

Yes. Members are allowed to bring in guests during Member Mornings. Please check with the Front Desk to find out which guests are covered by your membership.

Will I be notified when my membership is expiring?

We will notify you via email (be sure to check your spam folders) a month before your membership expires. Your membership’s expiration date is also located on your physical member card and displayed on the free eMembership card app.

Is my membership tax-deductible?

Please consult your tax professional.

What if I lost/forgot my membership card?

As a CMOSC member, you may present your photo ID at the Front Desk to access membership benefits.

I still have additional questions.  Who do I ask?

You are welcome to speak to the Front Desk staff in person, or to contact us via email at  members@cmosc.org, or by phone during regular business hours at (707) 546-4069.
