Styron, 34, and her husband, Henry, made the trip Sunday afternoon with their two daughters from their home in Summit Point, W.Va.
The family looked around the museum first since it was the first visit for the girls, their mother said.
"Our grandson, Ryan, is 5. He is really enjoying the cartoons and so am I," said Len Frank of Baltimore.
Frank and his wife also brought granddaughter Isabel, who is almost 2, but it may take a few years before she is truly able to appreciate a fine cartoon.
Frank spent some of his time Sunday afternoon wandering around the museum, which is located in Hagerstown's City Park.
"We've never been here before but this is just wonderful," Frank said. "It was built the year I was born, 1930."
Linda Dodson, educational coordinator at the museum, said she tries to do a children's film festival when she can.
"It's a great way to spend a cold winter day," Dodson said. "I'm enjoying it too."
Martha Trumble and her daughter, Jessica, 2, were also having fun at the cartoon festival.
Jessica expressed her preference for Goofy while her mom just liked seeing these old favorites again.
"I remember them when I was a little girl," Trumble said.
Madeline Styron, 8, and her sister Margaret, 6, seemed to be enjoying themselves as they sat on their parents' laps in the darkened viewing room.
"I like Goofy best," Madeline said.
And it didn't seem to matter to her that she couldn't put her finger on exactly what kind of animal Goofy is supposed to be.
After all, that burning question has been stumping cartoon enthusiasts for decades.
