Hi there Monica!
How exciting to be planning your first Walt Disney World vacation! Character Dining is such a fun way to meet the Disney Characters while enjoying a delicious meal! As a mom of four children including 9-year-old twin boys, I've always found there to be great Character Dining experiences that both my daughter and three sons can enjoy.
For a festive atmosphere, consider dining at Chef Mickey's at Disney's Contemporary Resort. This all-you-care-to-enjoy dining location traditionally features Mickey, Minnie, Donald, Pluto and Goofy. Another family favorite is 'Ohana's Best Friends Breakfast at Disney's Polynesian Village Resort which historically features Lilo, Stitch, Mickey and Pluto. Donald’s Dining Safari at Tusker House Restaurant inside Disney's Animal Kingdom Park is another great option for your daughter and son. Please know that Character appearances are subject to change.
I hope this information is helpful. Please don't hesitate to visit us again if you would like additional dining recommendations or have any other vacation planning questions. Best wishes for a magical first trip, Monica!
Bon Appétit,
Jodie
