I suppose I should mention that the operating word is theoretically. I'm also super aware that Disney is definitely not spending as much money and the thought of putting in something new that would cost *gasp* money is terrifying to TDO. So theoretically, Stitch's Great Escape looks great on a flyer or a trip planner as a thing for 5-12 males, but is not so great in reality. It's kind of like throwing a bone amidst attractions they are too young to appreciate and princesses.
And in concerns to MK having other stuff for this demographic, it's totally there, I agree, but Stitch at one point in his life was new and exciting and hot stuff. Also things like age and thrill capacity and height restrictions is another thing to think about. Either way you slice it, I know most of the 5-12 year old boys in my sister's elementary school would rather see Stitch than do the Swiss Family Robinson Treehouse.
But yeah, I totally agree, there are other "Boy" oriented things in MK, this is just one of the "newer" ones. (The fact that it's ten years old and considered newer is a problem).
Sorry if none of this makes sense, and I'm not trying to invalidate your points, I just think Disney believes they actually might still get some mileage out of this thing even though it should have died a long time ago.
