As for ordering only what you can eat - I totally agree, which is why I sometimes order child's portions, so I'm not wasting food. I like fries with my burger but according to your "logic", I should order a larger burger and forego the fries, which I enjoy and really want, because I'm an adult and the larger burger would fill me up on it's own. Ridiculous...
Exactly! If I am having chicken fingers or a hamburger, I want fries with it without being 1,000 plus calories. Plus, if it is hot as heck I want to nibble on a couple of things.
I have a question for the people who think it is wrong to order a kids meal - does this mean at the grocery store if would be wrong to buy kids aimed products (like cookies or lunchables or soup, etc) and eat them since you are an "adult" and these are made for children? What about if you have a "child" who would like to eat more than a kids meal - would it be wrong to buy them an adults portion or have them eat "adult" oriented food from the grocery store??

or...
What if a child's t-shirt fits you better than a grown up t-shirt? Is it wrong to buy the child's t...it does cost less...Or what about toys?? Everyone knows toys are made for kids only. Right?
As long as you are paying whatever anyone else is paying for the meal, there should not be anything wrong with it. If a kid buys the meal, disney gets the same money as if you buy the meal. If you do not want to buy a full adult meal and would rather go hungry than do it, than I think disney would be pleased to get the kids meal money out of you. If they did not want to sell it to a non-kid, they would do like TS restaurants do - you would have to have the child with you. I bet if it mattered to them, they would find a way to police it.
