- Use the table for two planned water and snack breaks instead of waiting for everyone to tire.

Quick parent answers
Does the FUNbrella rental include admission?
No. Every guest still needs waterpark admission in addition to the rental.
What is the main party day risk?
Hot weekend capacity and weather can affect entry and water time, so arrive early and keep guest communication clear.
What parents are saying
Parents get a shaded home base inside the water park, but the rental is only one part of the cost. Every guest still needs admission, and summer weather or capacity can affect the day.
