We just got back and I hadn't been since I was a kid. The parks all feel really different, and I think where you go depends on what appeals to you. Our favorite park was AK because the theme was really well done and the park is very lush and green. MK is definitely tops for kids. MGM and Epcot are the most adult. Our kids didn't love MGM but they have some good shows and the kids weren't bored. At Epcot, I let them poke around at some of the Flower and Garden festival stuff. It was very low key but they had fun. Since your child is so young, I would pick either Epcot or MGM depending on what is more interesting to you. If you are focusing strictly on your child, then I would do 2 days at MK.
