11. Bring Supplemental Food
If you think ordering an entree without a side isn't going to cut it, or if you usually snack between meals, go ahead and pack some supplemental foods from home. After all, the chips and fruit served in the parks aren't any different than what you might buy in the store, but they sure do cost more.
10. Enjoy Late Breakfast
Many of the meal options in Disney World are served buffet-style. This is awesome because it means you can really fill up during your meal. In order to take full advantage of this, try scheduling late breakfasts buffets. Breakfast is cheaper than lunch, but by eating it later in the morning, you can actually fill up enough to skip lunch entirely.
