Another thing you can do to get ahead of the food game is prepay for your meals at the parks. With a Disney Dining Plan, you spend about £45 for each adult (kids are about £16), which includes one table-service meal, one quick-service meal, and one snack. Visit the official Disney Dining Plan page for more information and to find out what plan is right for you.
Bonus tip: You'll still need to make reservations at sit-down restaurants, so you may want to do that earlier if booking your hotel less than 180 days in advance.
