Hi, Kiara!
Happy Birthday to your little prince! I think character dining will be a great way to celebrate a 4th birthday. Some of my kids' favorites when they were little:
Chef Mickey's at the Contemporary (breakfast or dinner)
Hollywood & Vine in Hollywood Studios with Disney Junior friends (breakfast or lunch)
Crystal Palace in the Magic Kingdom with Pooh and his silly pals (breakfast, lunch, or dinner)
Check through the
complete list of character dining locations. Once you decide, make sure to book your
dining reservations at these locations fill up quickly. Make note that you are celebrating a birthday. While in any of the parks, stop by Guest Services for a free Happy Birthday button.
If your son is a Cars fan, I suggest you go with the Cars Family Suite at the Art of Animation. It will be so magical for him to stay right in the heart of Radiator Springs in his very own Cars themed suite. Animal Kingdom Lodge is beautiful, but our kids are little for such a short time, enjoy the magic of the fun suite! Make sure to also stop by Luigi's Garage in Hollywood Studios for a chance to meet Lightning McQueen....KA-CHOW!
Whatever you decide, I hope your son has a magical birthday celebration in Walt Disney World!
