Olympus began Night at the Theme Park'', where select rides (Hades 360, Poseidon's Rage, Zeus, Trojan Horse Go-Kart Track, Underworld Go-Kart Track and the Kiddie Land Rides) would be open from 10 pm to 1 am for four nights weekly. People who would attend would receive free soda and parking. Nick Laskaris got the idea when he took his children to go see Night at the Museum: Battle of the Smithsonian at the local cinema. The village of Lake Delton did not approve the event, because it was in violation of its amusement ordinance in which businesses have to close around midnight and their 11 pm curfew law. Village trustees were worried about someone crossing the busy Wisconsin Dells Parkway at night and getting hit by a car. The village of Lake Delton subsequently made some changes to the amusement ordinance, with a variance for businesses if they requested, including Mt. Olympus. The village board had these changes on hold.
