I wish you the absolute best of luck getting someone at Disney to give this info out. I would love to know this as well, since I've been working at changing my eating style the last few weeks, and jogging as well. (so far lost 6lbs, yah! - only 24lbs more to go before the trip). I'm afraid of putting my system into a state of shock, w/o knowing the nutritional value of items on the various menus. I guess in case moderation will be the key. This is going to be REALLY hard!
I know at least one restaurant that refuses to give out this kind of info, Red Robin. I can imagine Disney following suit on this. I think also the problem is menu items at a lot of the Disney restaurants come and go. Let us know if you are able to locate this, though. Thanks.
