MOSI birthday party reservations can be made by phone or in person and are based on space and time availability. The base price of the birthday party is required to make the reservation ($225 for members, $300 for nonmembers). We require reservations be made within at least 2 weeks in advance.

There is a $15 cancellation fee for parties who cancel more than two weeks out and a 10% cancellation fee for parties who cancel less than two weeks out. If something has come up and you need to move your date, you can for no fee. If you need to cancel or reschedule, the sooner the better for our parties book rather quickly every weekend.

Late party arrivals risk a compromised time schedule. No refunds are available for late arrivals. A party will be considered cancelled if the Birthday family doesn't arrive within 25 minutes of the designated party time. If your party begins after your scheduled time due to waiting for late guests, you will have less time in your party room.

At MOSI, we have birthday parties down to a science! Our parties are designed to take the hassle out of party planning so you can relax and enjoy your child's big day. The experience begins with you and your guests celebrating in one of our private party rooms for 90 minutes. This will include activities according to your chosen theme, beverages, ice cream and decorations. Your guests will also receive group stickers that will allow them to enjoy the museum including Kids In Charge! for the whole day!
Each Party includes:

  • Enthusiastic party host
  • Vanilla ice cream
  • Choice of party theme with fun and educational hands on activity
  • Admission to exhibit galleries for you and your guests
  • Decorated party room includes: tables, table cloths, plates, cups, balloons and utensils in primary colors: red, blue, yellow or green. You may choose to bring a small amount of your own themed decorations and the party host will gladly help decorate the room for you.
  • Drinks: punch, soda and water (Coca Cola products)
  • Party room for 90 minutes-Please note parties with 30 or more guests will be using our larger room that is not decorated for birthday parties.

Your party begins with our host that will greet you in your designated party room in Kids In Charge! As your guests arrive before the party time, they will be allowed to explore Kids In Charge until your party begins. Once all your guests have arrived, our host will lead you to your party room. The host will then lead the children in an age appropriate activity related to your party theme. The host will lead in serving food and drinks and lead in singing once its time for cake and cut and serve it with ice cream. Lastly, the party host will take care of the set-up and clean-up of the party, leaving you peace of mind and more time to enjoy the day with family and friends!

MOSI does not permit outside food, with the exception of the birthday cake. Additional food is an additional cost and must be selected from our menu. Please notify MOSI if your guests have dietary restrictions. Please Note: all alcohol including beer and wine is prohibited. For more information, please contact Reservations at (813) 987-6000.

Since several parties are booked in a single day, the earliest you may enter the party room to set up is 15 minutes prior to your party's start time.

The Museum does not currently offer guided tours. Guests can enjoy more than 250 hands-on, interactive exhibits at their own pace. Children 12 and under must be accompanied by a parent or adult chaperone while exploring the Museum.

Your rental fee is good for up to 30 guests, not including the birthday child or their immediate family. For more information on larger parties, call reservations at 813-987-6000.

There are 3 parking lots located behind the museum. We ask that guests arrive at least 30 minutes prior to the party time to park. There is a $5 parking fee per car.

Not a problem! Your party rate fee includes all day admission to MOSI. Have your guests go to the MOSI Box Office for stickers. Make sure to let our staff know that they are here for a birthday party. You and your guests can enjoy three floors and two buildings of exhibits while you wait for your party room to be available. Special engagement exhibits are not included, but may be purchased at a MOSI group rate.

Balloons can be brought into the party room, but balloons are not allowed outside of the party room for safety reasons. This also goes for the balloons decorated in the party room. The only type of piñata allowed is the 'pull-string' variety. Piñatas that require being hit to open are prohibited.
