Hi Ana,
Welcome to the Disney Parks Moms Panel. I'm glad you stopped by because I want to let you know that if you don't plan to spend all 4 days in
Magic Kingdom park or add the Park Hopper Option to your tickets, you'll want to change your dining reservations to match your plans.
Any time you enter a theme park you need to have park admission. This includes the use of any dining reservations you have. So if you plan to spend the day in Epcot and you do not have the
Park Hopper Option added to your tickets, you'll need to plan for dinner in Epcot or at another dining location outside the theme parks.
I hope this helps clarify things for you, Ana. I can tell you that the
dining options in all four theme parks are incredible with many tasty options, many of which do not require a reservation.
Please let us know if you have any other questions as you plan your magical vacation, Ana. Have a Disney day!
Andrea U.
