I think this may sum up the dichotomy here. When my family went to Disney for the first time, my sister was 2. She loved Dumbo. She loved Pirates. She loved IASW. Now, 19 years later, she still loves Pirates and IASW. Not so much for Dumbo. While I respect that your children may love it now, is this something they will grow up with? Is there more to it than the fact Aladdin is generally about adventure. If you look to the original Adventureland, you started out in a Caribbean area. That progressed into a more Polynesian area as you moved in, with a large island separating it. Then, on the other side, you walked down to a jungle covered river. Of course these themes didn't match, but they worked together with transitions. While there was a hodgepodge in a way, you never doubted which land you were in. The attractions, the architecture, the music all blended to create the feeling. Will the average 2 year old pick up on that? no. Will the average 12 year old? Maybe, but doubtful. Will the average 42 year old? maybe yes, maybe no. But, for those that do, it added a level of appreciate very few places have. And, a lot of adults, my parents included, didn't realize it until it was explained to them, but they absolutely had the feeling (even if only subconsciously) since they went the first time in '74.
I am not trying to downplay the enjoyment of your children. I think that is an ABSOLUTELY necessary element of the Disney experience. However, when you start to make the themeing more shallow, the focus solely on the characters which are kid-focused, you start to destroy the entire point of the Disney park experience. It was not meant as a place for kids. It was meant as a place for families to all ENJOY. Can you enjoy watching your kids have fun? of course. But, if you can create attractions that speak to and appeal to the larger audience; the base interests everyone shares growing up (whether you have already or are in the process of doing so), then you've got magic. It's not geeking out. The geeking out part is deciphering it and figuring out why it works. And, I would posit that that's what Imaginneering is all about and why those 9 old men were so successful. If that's geeking out, sign me up because they do a pretty darn good job at it.
