Id estimate that two far larger forces are in effect for Disneyland than people not paying their morgage. (though I suspect a few are living large on the hog with borrowed time/money)
1) The dollar is low right now. This means other people come here, and we stay here.
2) In tight times like these, people cut spending on the kids last. Sure it is frivilous spending, but it is all ok, cause it is for the kids. (Think of the children, man, Think of the children! )
Also, this was the weekend before Halloween. My brother has two little princesses at home, and both went to Disneyland this week. In comparison to Florida last year, two days at Disneyland is dirt cheap. (and yes he is still paying his morgage)
