Hello Friend,
Your trip is coming up so soon, you must be getting very excited! I did many
character dining experiences at Walt Disney World with my daughter when she was your son's age. I believe that the character meals that he will enjoy the most depend on which characters he knows and wants to interact with. While they are all fun, I suggest that you browse the link that I provided to see if there are any that are especially appealing to his interests. Let me offer you some of the character dining experiences that we enjoyed the most when my daughter was young.
Disney Junior Play 'n' Dine at
Hollywood & Vine at Disney's Hollywood Studios gives children a chance to interact with characters from Disney Junior shows such as Doc McStuffins and Jake and the Neverland Pirates. New at dinnertime, Hollywood & Vine sees Minnie Mouse hosting seasonal celebrations with her friends. Another favorite for my daughter when she was young was
Cape May Cafe at Disney's Beach Club Resort, where Minnie Mouse and her friends appear in their beach attire at a fun buffet breakfast. Please do note that all character experiences are subject to change.
Because character dining experiences are so popular, and because you are so close to your travel date, I suggest that you head to the link that I provided at the beginning of this answer to choose a character dining experience and make a reservation as soon as you can. You might find that availability is limited this close in, so I suggest being flexible with both time and restaurant. I am sure that you will have a great time whichever character dining experience you choose!
