Adults that go 500+ miles to Disney multiple times a year?

Anybody know any people like this? I know a few people that go 600-800+ miles to Disney 3-4 times a year...just adults no kids. One of the wives will post pics there all the time maybe with face paint/mickey ears/characters in the pics saying it's her favorite place....of course the hubby pulled into a lot of them.

Is it mental illness or just a good escape from life?
