Solo in Disney is my favorite way to do it. I went for 10 days solo this past November, and had a blast. It was so relaxing and very liberating to go where I wanted, when I wanted. I met so many new people, met up with friends who were down the same week, went to Uni/IOA one day. It was one of my favorite trips yet. I love waking up early in Disney, so being able to wake up and go without having anyone else to worry about, was great. I would explore the parks, get a snack and sit on a bench and just relax and people watch without anyone rushing me to the next ride/attraction.
