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.

Liked the decor of the island and the music. Limited options for slides, small waterpark compared to the Dells. Some trash lying around. Purchased the shaved ice at $4.00 and was told she had no spoons..overpriced. Cute gift shop.

I have 5, 3, and 1 year old daughters. We are from the south so the water was a huge "shock" for us. LOL. But my girls and I had so much fun! I like how one area had two "decent" size slides for them...More

My husband and I took my teenage son and 4 of his friends to Lost Island and everyone had a great time. The only thing my husband and I wish they had was a swim up bar. Though there are several huts with alcoholic/non-alcoholic drinks...More

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.
