My mom will be so thrilled to hear this! Once they took McDonald's out of Epcot and replaced it with a more healthy kiosk, I've been so happy. You still have options to eat Mickey Ice Cream ears, and still promote healthy snacks. So smart that they're adding this.
Only at AK for now; I actually just asked last week if more were coming to the other parks. I was told "not at this time," for as much as that's worth!
