Hi Poonam,
Welcome to the Disney Parks Moms Panel!
Given the ages of your children, I suspect that you have plans to do several character meals. These can be more expensive than a standard table-service meal. We always prefer to use a dining plan because it is such a great value for our family. When our girls were about the ages of your little ones, the Disney Dining Plan was perfect for us. With one quick-service and one table-service meal plus two snacks per night, we had some great dining experiences. We have enjoyed 1900 Park Fare, Chef Mickey's, Cinderella's Royal Table, Akershus Royal Banquet Hall, Tusker House Restaurant and Hollywood & Vine.
We also find the dining plans to be a great value because they include beverages with meals and the resort refillable mugs. To be sure that we are getting a better value with a dining plan, I always make our dinning reservations for table-service meals, then make tentative plans for quick-service meals. Then I check the restaurant menus to get price estimates. For character meals, I always call and speak to a cast member in dining at 407-939-1947 to get pricing for the dates of our trip. And, I include an average drink estimate at $4/non-alcoholic beverage for each meal since without a dining plan, drinks can be charged separately. I estimate snack prices to be about $5 per snack. Check the Be Our Guest Restaurant
breakfast menu to get an idea of the pricing.
Poonam, for me, a dining plan also relieves some of the stress I have about food. Each person gets her or his own meal. I do not have to worry about dividing food. At character meals, each guest 3-years old and over has to pay for a meal, so since we do so many of those, we would not see much savings. For us, a dining plan provides a more stress-free experience!
Magic, memories and Minnie Mouse hugs,
