This is a great activity for a family. We went 2 days in a row from opening time to closing time. There are plenty of exciting rides to occupy the time. The wave pool is a blast!

The parking was easy. The options for slides, wave pool, kids areas, and lazy river were great for the kids. The boys thought parts of it were equal or better than the dells.

I love Lost Island. I make an effort to go at least once every summer. We live close by so it's a quick, easy drive for us. The admission price doesn't seem expensive to me because it takes a lot to maintain that many slides....More

I took the Grand daughter for a treat. She was excited and I was tired by the end of the day. Check off my bucket list.

Since it is 95 degrees here, I assume for a Floridian, it will be refreshingly warm enough.

Jami - The deluxe cabanas are located on our elevated deck removed from the action of the park. If you would like to be near the wave pool you will be most interested in our floor standard cabanas.
