That is a great park, been there twice, but not at peak times. It will be chockers.
They are very organised owners. The rather fussy rules about camping inside the red lines, which are x amount inside your site boundary, would be a bonus at busy times preventing disputes and making it easier to get between sites. I suspect they would handle the crowds really well. They escort you to your site and make sure it suits and that you understand how it works. Good camp kitchen. Excellent pools. Excellent beach access. Kids activities during school holiday periods, so you may actually get them off your hands for a bit. Small shop for essentials and basic take away tucker. Lots of Roos.
I reckon you should just go for it.
