Hi Jessica:
There are few things my four year old and two year old boys look forward to more on their Disney trips than character dining.
For a character meal for dinner, my family's number one stop would be
Chef Mickey's at the Contemporary Resort, which is also open for breakfast. My boys not only enjoy the huge buffet, but their smiles shine when Mickey, Donald, Goofy, Pluto, and Minnie stop by the table to pose for pictures and sign autographs.
Another great character dinner experience my boys enjoy is the
The Garden Grill restaurant in Epcot, featuring Chip 'n' Dale and friends such as Mickey and Pluto. Not only does the restaraunt rotate, but we find the characters to be among the more interactive of the character dining options.
For my boys, the character meals at Cinderella's Royal Table at the Magic Kingdom, 1900 Park Fare at the Grand Floridian Resort, and Akershus Princess Story Book Dining at the Norway Pavilion at Epcot are too princess and storybook themed for their taste. However, every family is different, so choose the character meals that look right for your family.
Keep in mind that the characters are subject to change and that character meals tend to book quickly. I highly recommend making advance dining reservations soon. You can do so online
here or by calling (407) WDW-DINE.
Enjoy your vacation.
