I assume you are talking about the baby centers, right? I have used the one in MK-next to Crystal Palace, by the restrooms and the one in Epcot- by the entrance to WS. Both are great places for changing and feeding little ones. There are full size changing tables, high chairs, a seperate bathroom, an area for toddlers to sit. There is always a CM there. There are supplies(formula, baby food) available. There is an area to warm the food, if necessary. There is a private room for nursing. I think they are great and well equiped.
Have fun-
