Party Policies & FAQ

Party Policies


A NON-REFUNDABLE $50 deposit is required to reserve your time and date. A confirmation letter will be sent upon receipt of deposit. The remaining balance is due with your final guest count and show choice one week prior to your scheduled party date. Payment can be made by cash, check, or credit card (Visa or Mastercard).

If final payment is not made one week prior to your event Chabot will automatically charge the card on file Wednesday before your party.


We ask that you not bring balloons, glitter, confetti or piñatas. These items can be blown into the forest and cause harm to the animals.


We do not allow outside entertainment.

Guest Check-In & Parking

Parking is free at Chabot Space & Science Center. Upon arrival, check in with Visitor Services and receive your group tickets (your reservations will be under the birthday child’s name). UNDER NO CIRCUMSTANCES ARE PARENTS TO DROP OFF THEIR UNESCORTED CHILD(REN) BEFORE YOU ARRIVE!

We appreciate your interest and look forward to celebrating with you at Chabot Space & Science Center!

Party FAQs

Q: Who is counted in the 20 people covered by the birthday package?
A. All children 3 and up and all adults are counted toward the 20, including the birthday child and his or her family. If the birthday family has a membership, the people covered by the membership are not counted toward the 20. Guests who are members are still counted toward the 20.

Q: What is the cost of extra guests?
A: If the guest count is over 20 people we charge a per person fee based on the age of the guest and type of birthday activity. The cost for extra adults is $10 regardless of the birthday activity. Below is a list of fees based on each extra child and the birthday activity:

  • Cosmic Package = $10 per child
  • Cosmic Deluxe Package = $12 per child
  • Slimy Science = $16 per child
  • Pop Rockets = $16 per child
  • Polar Ice Cream = $18 per child

Q: What if I have last-minute guests that RSVP, can I pay for them at the door?
A. Yes, you can pay for them the day of the party. We ask that you pay for all extra guests in one payment.

Q. Is there a host in the room?
A. There will be a Chabot staff member assigned to assist you throughout your time at the Center. This means if you need help this person will help you, otherwise these are self-guided parties. If you purchase a birthday package with an activity, a Birthday Guide will organize and manage the entire activity.* A staff member will help you find your assigned area for Table Time, but will not be present in the room during the entire period. Nor will they assist with set-up or clean-up.

Q. What is Table Time?
A. Table Time is a separate time for you and your guests to enjoy lunch & cake. It is held in a private space that you may decorate (either a classroom or café tent depending on availability). You will be given 15 minutes prior to your table time for set-up. Clean up must be completed by the end of your table and all guest are to be out of the room at the appointed end time.

Q. Do all activities and shows need to be done within the assigned Table Time period?
A. No, the time required to perform the birthday activity, see planetarium shows and enjoy our Center is separate from Table Time. Your guests can enjoy the center for the entire day if they like.

Q. Can we open presents at the Center?
A. No, we do not allow presents to be opened on site. We do, however, offer a storage bin for all of your gifts to be held in until the end of your party.

Q. Do you have a refrigerator to store a cake?
A. We do not have a refrigerator for your food but can supply a storage area and cart to store your items until needed. You may bring in a cooler or ice chest to keep food or drinks cold.

Q. Does Chabot supply gift bags?
A. Gift Bag options are available at the Starry Nights Gift Shop. You can purchase $4 bags or $7 bags (both priced at 30% off from retail) or come in and create your own!
Call or email the store for details: (510) 336-7302 or StarryNights@ChabotSpace.org

Q. What supplies do I need to bring?
A. You will need to bring the following items: paper plates, cups, napkins, silverware, decorations (no confetti or balloons), birthday cake, candles, and matches or a lighter. The Table Time locations are equipped with tables and chairs.

Q. Does the visit include a docent tour?
A. No, the exhibits are self-guided.

*With the exception of our Cosmic Deluxe packages which are intended to be self-directed activities.
