Jonathan Cobb and his family arrived at Disney World on Saturday after a 10-month journey from Disneyland California to the Sunshine State.
The father remembers the quote being on the last Father's Day card he received from his 8-year-old daughter, Julia.
"She hobbled down the hallway with an IV pole and could barely walk," he said, "and it had one of my favorite quotes on there from Walt Disney. It said, ‘If you can dream it, you can do it.'"
Julia died from Ewing sarcoma, or bone cancer. She leaves behind not only her parents, but two sisters and a brother. Her death sparked the entire Texas family to honor her by visiting a place she loved.
"Julia taught us well – to go to your happy place – so naturally when she passed away, it was, ‘let's go to our happy place.' We just chose to walk to one happy place on Earth to the other," Jonathan Cobb said.
Jennifer Cobb, Julia's mother, says she lost her daughter on the last day of her Make-A-Wish Foundation trip to Disney.
But, the 4,000-mile trip wasn't just to honor her daughter, it was also to raise awareness for the disease that took Julia's life and to help other families battling cancer.
"I cannot bring Julia back," Jonathan Cobb said. "I can only walk forward and change the future for another family or for my own family for that matter, and give them a foundation of hope from which to build upon."
