I also agree about getting kid's meals because the portion sizes are just right.
The Liberty Square Market at MK has a baked potato that is only around $3. Most of the food courts have a soup option that is really inexpensive. I love soup so that's always a good option for me. When we stayed at AKL a few years ago, Mara served the same soups that they had a Boma. So good!
Also, you can order a la carte at the quick service locations so we will often just get one fry to share. It saves money and calories!
thanks!
