Hi Susan, Thanks for visiting the Moms Panel!
Chef Mickey's for dinner is a fantastic choice. The buffet has wonderful selection and the "Make-Your-Own-Ice-Cream-Sundae" bar is always a hit with the kids. If you click on this link
HERE you'll see the containers holding some of the sundae toppings on the left behind Mickey. The character interaction is fantastic and the atmosphere is always a lot of fun.
For boys ages 4 & 1, I would recommend the Crystal Palace for breakfast. Your boys will visit with the lovable Winnie-the-Pooh, Tigger, Eeyore and Piglet. See:
HERE. Located in the Magic Kingdom, this "must do" for our family has a beautiful setting, a superb breakfast buffet and offers fun times with the characters.
Hope this helps and have a magical vacation!
