Hi Andrea,
If your boys are fans of Disney Junior then
Hollywood & Vine at Disney's Hollywood Studios is an excellent choice for a Character Meal!
Character dining at this dining location is available at both Breakfast and Lunch.
At Breakfast, you can start your day with song! Guests are able to sing
along with their hosts to familiar Disney Junior tunes whilst savoring a
delicious breakfast buffet featuring favorites like Mickey Mouse-shaped
waffles, frittatas and fresh fruit.
At Lunch, the Disney Junior pals continue the
festivities with more singing, dancing and playing. Across the
lunch buffet you will find kid and adult friendly entrees, such as baked
chicken and assorted deli selections.
Although characters are always subject to change, you can usually see June, Handy Manny, Agent Oso and Jake here.
The only reason why I didn't mention this particular Character Meal in my answer to Sarah from IN was because I was talking about some of my family's favourites Character Meals and as my Son is now 9-years old, we haven't experienced a Character Meal at Hollywood & Vine for quite a few years.
Wishing you a magical trip filled with memories which will last a lifetime!
