Hey there Tatyana! Purchasing the Disney Dining Plan will give your family the opportunity to "taste" your way around Disney World without having to stress about budgeting or paying out of pocket. You will only need to purchase a plan for three of you since the 2-year old will eat for free, by sharing off of your plate. She will also be permitted to eat from the buffet free of charge!
I would actually recommend the
Disney Deluxe Dining Plan. This plan offers each member of your party 3 table service meals a day and includes an appetizer, entree, dessert, and non-alcoholic beverage in addition to 2 snacks per day each.
Signature dining experiences such as Cinderella's Royal Table cost 2 meal credits, so since this plan offers so much food, we will opt to use a snack credit to purchase a light breakfast such as a muffin or pastry on several days. This saves us meal credits which we use toward 2-credit locations.
If you wish to purchase a totally all-inclusive meal package, then you may consider the
Premium Dining Plan which also includes 3 meals per day and 2 snacks. With this plan, Signature Dining experiences only cost one credit as opposed to two.
Honestly, my family loves to eat and we always have plenty of credits with the Deluxe Plan, and it's not uncommon for us to have a few leftover, even when dining at Signature locations! It really is a lot of food!
Best Wishes,
Amanda F.
