Birthday Party FAQs

  • For Birthday Parties held at the Museum, do you allow decorations? Outside food and beverages? Outside entertainers? Music?
    • We’re sorry, but decorations other than table toppers are not permissible.
    • Outside food and beverages are allowed. Due to safety purposes, heating equipment is not allowed. We recommend providing a cooler with ice to keep items chilled. Alcoholic beverages are strictly prohibited.
    • We’re sorry, but outside entertainers and/or performers are not permissible.
    • Music is allowed in the party rooms, however, we kindly ask that you play music that is appropriate for children.
  • What are your policies on deposits, cancellations, rescheduling, and inclement weather for birthday parties?
    • A 50% non-refundable deposit is required at the time of booking and all remaining balances are due one week prior to your scheduled party.
    • A rescheduled party must be rebooked within one month and be held within six months of the original party date.
    • If, due to inclement weather on or around the date of your reserved party, you feel the need to cancel your party, Port Discovery Children’s Museum reserves the right to retain your deposit if the Museum is officially open for admission on the day of the scheduled party. In the event Port Discovery Children’s Museum is officially closed, we will reschedule your party for a later date.
  • How many guests are permitted for birthday parties?

    Celebration party rooms have a maximum capacity of 45 people total. Packages include admission for 20 people (children and adults). Additional guests are $26 each. Please note that we require strict adherence to guest attendance due to capacity restrictions and safety protocol.  Each and every guest, including your birthday child, their siblings, and parents, are included in the total number of guests for a party. Children under the age of 1 are free but are counted towards admission.

  • Do you provide additional time for the setup/breakdown of Birthday Party rooms?

    We’re sorry, but we are unable to provide additional time for setup and/or breakdown. However, our Party Pals are available to help you with setup, breakdown, and any other party needs, and will do their very best to ensure you are able to make the most of your time in your private party room.

We offer discounted parking for your party guests at this location only.

  • Do you have a space to store our items if we arrive early and/or would like to stay after our Birthday Party ends?

    Yes! We’re happy to provide storage for party items so that you can enjoy time in the Museum before and/or after your party. Valuables should be stored separately in our lockers located near the entrance of the Museum.
