I'm 42. I love Disney, and I love theme parks in general. I just adore thrill rides and roller coasters - not that many of those at Disney but there's something really special about it anyway. I love the escapism, the theming, the sheer joy and excitement of it all. They do theming SO well at Disney, especially in Florida...I think someone upthread said that all the worries of day-to-day life just melt away and that's so true.
I have been to Orlando twice and neither of those times was as a child, though I was desperate to go when I was younger. I went in my 20s and a couple of years ago, for my 40th birthday. I preferred the Universal theme parks when I was younger, and I do still love them, but Disney has grown on me. Massively. So much so, I even unexpectedly felt a bit emotional when watching the parade on our last day at Magic Kingdom.
We also went to Disneyland Paris last year and I loved that, too. I have a Mickey Mouse sweatshirt (wearing it now, actually), and some PJs, but I'm not into Disneybounding. I could perhaps be persuaded to wear some ears but they'd be Mickey ones, not Minnie ones.
Regardless, I don't really get the Disney-bashing on this thread...just let people enjoy what they want to enjoy. I don't lack emotion or maturity or intelligence. I have a job, and a daughter, and I also enjoy literature, camping, running, music festivals and countless other things besides.
I can't wait to go back to Disneyland Paris and Orlando and really hope I get the chance to do both again.
