Hi Gabriela, Thanks for visiting the Moms Panel!
The two character breakfasts that I would most recommend for kids those ages would be Chef Mickey's in the Contemporary Resort (see
HERE) and the Crystal Palace in the Magic Kingdom (see
HERE).
Our children enjoy both of these buffets, as they feature wide varieties of delicious food. The character interaction is wonderful and both offer a fun atmosphere.
While characters are subject to change, Chef Mickey's generally has Mickey Mouse, Goofy, Donald and Pluto. The Crystal Palace features Winnie-the-Pooh, Tigger, Eeyore and Piglet.
Hope this helps and have a Magical vacation!
Kaylene
