Factual error: The family passes an exit for Carefree Highway. This is an exit off I-17 a few miles North of Phoenix. At that point they would be about 10 miles from Scottsdale. Yet they drive all day and that night they are still within scooter range from Scottsdale.

Other: When they arrive at the motel, the mother says that the grandpa is in room 13, but when he opens his door it is room 208.
