I have two kids that are 2year old do I need to get tickets for then to take them in the water park with me

2 yr olds and younger are free. If you have a child that is 5 you can get the a preschool pass, they will get SeaWorld and Bush gardens free and if you want you can add Aquatica for $60

Not until they turn 3

Children under 3 are free.

They do not need a ticket until they turn 3

I dont think you need a ticket for 2 year olds
