What's Included
Here's how we party!
Funplex parties are easy for you and unforgettable for your birthday child!
- You’ll have a dedicated party host for two hours who will manage the flow of your event and guide your guests through the attractions and activities. Your guests will do the attractions first, then enjoy pizza and cupcakes, then they will go to the arcade.
- Your party includes a reserved table in open seating or a private room (depending on the package selected).
- Paper party supplies are provided so you don’t have to bring anything unless you want a specific theme.
- Each child will receive pizza, a drink, and a vanilla cupcake. For adults, you can order from our discounted catering menu.
- FREE birthday child! Your guest of honor is free and does not count towards the 10 children included in our packages.
