When can I enter the park?
While parties will be reserved at designated times throughout the day, your admission tickets are valid for the entire day. You may enter the park at normal opening time, but you will not be able to access your party pavilion until your designated party time. We encourage guests to stay and enjoy the park after your party time ends.

Can my guests pick up their tickets any time throughout the day?
Tickets included with your package will not be available until the remaining balance on your reservation is paid. Once this has been taken care of, then all tickets will be printed and given to the birthday event organizer for distribution to guests. If the event organizer wishes to leave the tickets for guests to pick up, then a list with names will need to be provided to ensure that tickets are distributed appropriately.

Can I access my party pavilion early or stay after the party time?
Neptune Island schedules multiple parties throughout the day. Early check-in or late check-out of your party pavilion is not available as other parties may be taking place before or after your event and staff must prepare each pavilion before and after each event.

What does the “up to 25 guests” mean in the birthday package? I thought only 11 admission tickets were included.
Each of our party pavilions have a maximum capacity of 25. Please do keep in mind that any additional tickets will need to be added for any guests over the included 11 admission tickets. Birthday reservations may not exceed 10% of original order and no more than 25 participants in total with the Captain’s Celebration package.

Neptune Island Waterpark may not be able to accommodate any additional add on pizzas requested with less than 72 hours advance notice due to inventory supply chain lead times.
