We booked our trip from a promotional email I received. I guess for the price I should have had low expectations. Our room was off site and was awful. The beds were lumpy with just a thin blanket. The building had a bad smell being covered up by a lot of air freshener. Also, none of the doors were marked... More

We were so excited about finally visiting the dells but I'm pretty disappointed. Our off site hotel was ok, but definitely overpriced. Mount Olympus indoor water park was nice but smaller then i thought, especially considering the amount of ppl going in and out. There isn't enough room for everyone. There wasn't enough staff. Ppl were hogging the floats, which... More

There are plenty of roller coasters, go-kart tracks etc but you still get water slides, wave pools and more. Great park. A can't miss if you're going to the Wisconsin Dell's.

This is our 2nd time staying with Mt. Olympus, this review is for the indoor water park. It's got a great area for little kids 2-8 to pay with different types of slides that end up in shallow water. My 3.5 year old daughter spent hours and hours and met many different kids to play with. She loved every minute... More

I feel they should have a limit to the amount of people that are allowed in. The lines were insane! The pools, and rivers were so crowded you didn't want to go in. I felt the cleanliness in the indoor water park was awful. I would NEVER go back to this cesspool. Some interesting rides, but Noah's Ark is way... More

The indoor water park is smaller than the other places that we go to but was great for little ones. There is 4 water slides and they were ok we did have fun for the price it was worth it. The amusement park was also geared towards the little ones.

Took a trip to see the ice castles at Mount Olympus park. It was an interesting set up and great for young kids as there are ice Slides and ice tunnels which they will enjoy. Be sure to wear your outdoor winter clothes as it is very chilly but fun and worth the trip.

Our kids are 6,7,8 years old. This is our 4th year coming. It will be our last. Our kids outgrew the water park and amusement park. It served its purpose when the kids were young. Now we will spend a bit more money and go to a nicer place. It's not a bad place and prices are good. If you... More

Lots to do. Great lazy river inside and out. Tons of waterslides. Two wave pools that have some awesome waves. Food is pretty expensive and entrance/ exit is on a big hill.

Thank leartruck
