The strollers at MK, Epcot, and AK are the same. MGM has different strollers, they look like jogging strollers. These strollers are not as good as the others in my opinion. They should both be able to fit into the strollers, except at MGM. Also, MGM's have a 30 or 35 pound weight limit. The strollers may have some problems if a child weighs more than that.
