Bought tickets in advance and got lucky on a weekday that wasn't too busy. The line to the new slide was still too long and none of the other new indoor attractions were completed. One of the main rollercoasters was also under construction so we didn't get to do 2 of the main things we wanted to. Everything else had decent lines though. Food is about what you would expect. We got a whole pizza which was the best deal by far but not even on the menu. They could use a few more restrooms and "you are here displays" since you have to ask for maps now and they are only available at the gate. Also somewhere outdoors to just rinse off, some mist fans and a few more food carts would be nice. Fair warning, their underground rollercoaster can be scary even for adults, not to mention loud underground & jerky as it is wooden but worth trying just worth a long wait. Overall not a bad choice if you're going to the Dells.

I booked my tickets online. When I checked the room that I was given I was highly disappointed the carpets were disgusting and the room smelled funky and you could tell they didn’t even cleaned the windows or mirrors. I went to complain to one of the persons that checks in people and she gave me another room at a different location that they had and I was happy with the outcome. They didn’t give me a hard time at all and were able to find a resolution to my problem. I was happy and my family had fun at the water park and the roller coasters. I had a great time here. Just remember not to book a standard room because those normally have carpet. It would also be nice if the other buildings had a guest laundry the one we stayed at didn’t have one.

The kids had a lot of fun. But very long wait lines, and way over crowded. We went on a Saturday. Over all it was a great trip we just didn't get to do much because the lines were so long and we only had about 5 hours and waited an hour to ride go carts. The wave pool was AWESOME, I'd say that was all of our favorite part.

Of all the things to do in the Dells Mt Olympus was by far the most fun for the money. Bout 35 bucks a person for the whole day of both theme park and water park. The roller coasters were a blast of fun, such a thrill ride felt like my heart was ready to jump out of my chest, like we hit the reset button felt great. The water park was a great follow up, the lazy River really booked quick. Getting to the big wave pool was the best, rather than a bunch of waves it does one huge 4 foot wave every couple minutes. Everyone gets close as they can to feel the giant wave pick them up and drive them back 20 feet. So much fun, highly recommend making Mt Olympus a day trip while in the dells.

Majority of the roller coasters there were very fun! Have a variety of go gart tracks! Didn't do swimming/waterpark stuff. Not much shade anywhere. Indoor theme park was boarded up. The waterslides that used to be on the hill-all gone now. A restroom was dank/old. Don't go on Pegasus! That coaster was bumpy, jerky, not fun nor pleasant At All-Terrible ride... Zeus & Cyclops was great!!! Hades was fun But... I'll let you experience that for yourself. It would be awesome if they had more amusement rides.

Theme park was great! Waterpark was basically not usable due to the water temperature being torturously cold. And this was in the middle of June. Luckily the kiddos, four to fourteen, loved the rides at the theme park. Parks were nice and clean. Employees were very courteous and helpful.

We bought tickets on Black Friday, so they were like $5 which who can complain… but parking is $30, each meal was about $20, drinks were $4 each… typical waterpark prices…. Older facility.

Indoor adventure park is closed. Indoor waterpark is closed all but one slide. Skywalk is closed connecting the hotel to waterpark. The hotels are not connected to the parks as advertised . No shuttle service so get on your walking shoes! most rooms about a mile or so away. WiFi doesn’t work to even download a email.Floors are so dirty in rooms you can watch mud run off your feet. There is hair all over the floors from some type of animal feces and someone else’s leftover cheese. Look at photos. Air conditioner units have no remote and are too high to reach and sound like a freight train. Daily an hour to 4 spent waiting to get new wristbands because they don’t work and you get locked out of your room. Daily!!!!!! Call customer service and Stand by your door and wait for no one to come. For hours! Horse ride by the front entrance that draws people in is down. So overcrowded it’s seriously pathetic because half the parks down! Horrid place!!!! What a joke
