Went to Mt Olympus mid week July 9-11. Think this is the best time to go. Avoid a lot of the crazies that show up on the weekend. Hotel room was large and spacious. We had four adults and two kids (who slept in the bunk beds). Water slides were phenomenal. There were lots of rides for all ages. Lots of life guards around all the water rides to help keep everyone safe. I came off one water slide and was totally disoriented when I hit bottom. The life guard fished me out and sent me on my way. Not a lot of places to eat inside the park however and food prices were kind of high. After we checked out of the hotel we drove to the other side of the park and parked in the larger parking lot to be closer to the rides. If you do this park on the lower parking lot unless you are ready to hike up and down the steep walkway right inside the entrance. The park is well laid out, not so much the parking lots. Found them to be very confusing. Well worth the money for our group which ranged in age from 68 to 9.
