History of the holiday
The holiday was established in 2017 by Kalahari Resorts and Conventions, one of the largest indoor waterpark chains in the U.S. The goal was not only to celebrate summer vacations but also to highlight the importance of waterparks as places where family memories are made, as well as to stimulate interest in visiting such resorts.

* special discounts and promotions for waterpark entry;
* family events, competitions, and water games;
* prize and gift giveaways;

Significance of the holiday
