I took my daughter to Disneyland when she was 2 for the first time then both her and my son again when she was 4 and he was 2. They LOVE Disneyland, however we lived in California. It really depends on your son, my son has always been pretty mature and still remembers everything from that visit 2 years ago! I think he would have a blast but I would recommend Disneyland, its much better because you dont have to go to 4 parks, so its easier for the smaller children.
