Hi! I've traveled solo to WDW 5 times (soon to be 6), and nativetxn's suggestions show how everyone's different! MGM is my least favorite, I find the pathways too narrow. I love the other 3 parks. At Animal Kingdom, the scenery is so beautiful, and some of those animals you can stand and watch for hours. One time I spent close to an hour just watching the birds in Pangani Trail. At Epcot WS, you can shop in all the pavillions without anyone tugging at you. At MK, because it seems to attract the most families, I like to grab a rocking chair (like Samantha Brown once said, "I brake for rocking chairs") and do some people watching. For people-watching, MK can't be beat. Actually, at MGM, hanging around the sorcerer's hat or Animation Courtyard is fun, or sitting on a bench on the main street there, hoping to see some streetmosphere characters. Actually, there's no bad place to go when you're solo.
