The contest involved a mystery man walking the streets of the city waiting for someone to ask the secret phrase: "Have you been to Dallas lately?"
Wright said the fourth person they asked revealed himself as the mystery man.
"I'm homeless and I thought someone was just messing with me," Wright said Sunday on WLUK's "Good Day Wisconsin."
"Then we saw the cameras. We had 90 cents in our pockets and we have won a package that people would have offered thousands of thousands of dollars for," she said.
The couple initially worried they wouldn't be able to afford the trip, but the Dallas Convention and Visitor's Bureau announced during Sunday's broadcast it has decided to cover the pair's airfare.
"I promised myself I was not going to cry and then you go and do this," Wright said.
