For more than 30 years, thousands of locals and visitors have driven through the park for the lavish light displays, to see the famous bearded man and to get a Cherry Mash from a local group.
"Giving back to the city, and you would not believe all the smiles on the kids' faces when they come through," said Bob Hamm.
The Optimists Clubs of St. Joseph has been part of Holiday Park since day one.
The organization collects donations that go toward new lights for the park.
"We have to replace a lot of lights. There's a lot of lights that get broken, unfortunately, through the season," said Max Van Dyke.
They are also looking to replace the old incandescent lights with LED lights, which are more energy efficient and typically last longer.
"The ones here on the castle are the new LED lights. Those are the only new ones this year," said Van Dyke.
But soon, the group says with the help of donations, the whole park will be lit with LED lights.
"People think they're obligated to give us money. We're just glad you come through, and had a good time," said Hamm.
Last year, they raised thousands of dollars for the park.
They don't have a specific goal this time around, but they hope to see big numbers.
"The more [money] the better. We'll put it to good use," said Van Dyke.
Holiday park is open from 6 p.m. to 10 p.m. every night until January 1, 2014.
Hyde park is also lit this holiday season.
Admission is free for both parks.
