My brother always thought the desert scene was Yuma, AZ with the military jets. He trains there regularly and thought it looked just like it.
When he saw the desert- he said "that looks like Yuma". When he saw the planes he said "yup, that's definitely Yuma"
The skiing could have been Colorado, the surfing in Hawaii, the oranges in Florida, and the rafting in Montana.
Note: my brother isn't an idiot, nor geographically challenged. He just didn't know that it was a "port" from the California version.
Although, I do agree with
@DisneyExpert that the Christmas Main Street is a cheap effort and look forward to a much better film.
