We were there in October and ordered room service twice, once for dinner and once for breakfast.
For dinner we had one club sandwich, one cheeseburger and one kid's grilled cheese. Each came with fries. I can't remember what else came with the kid's meal, maybe fruit?
For breakfast we ordered my DD (2) a Mickey Waffle since I had promised her one and had not been able to follow through until that last morning.
Portions were good sized, similar to what you would receive at any restaurant. Lots and lots of fries. We were not able to finish all the food.
HTH!
