Hi Manuela!
The included restaurants for the Disney Dining Plans can be found in the links detailing each of the plans.
Each plan offers different features. The
Quick Service Plan includes two quick service meals and 1 snack per person per night of your stay. The
Dining Plan includes one quick service meal, one table service meal and one snack per person each night of your stay. The
Deluxe Plan offers 3 meals, 2 snacks and one resort refillable mug per person each night of your stay. The
Premium and
Platinum Plans even offer recreation and entertainment. In each plan, you'll see the listings of participating restaurants.
You may leave and return to the
same park on the
same day without having the park hopper option. So, for example, you can leave Magic Kingdom to head back to your resort for pool time, then go back to Magic Kingdom later in the evening to enjoy the fireworks.
Have a magical vacation!
Amanda
