Over the years, I've made solo visits to MK, EPCOT, & DHS (as well as USF) on various occasions. I also went to DL/DCA in CA by myself last year. All of my solo trips were because I had business with or was performing at Disney and had some free time. Any "vacation" trip has always been with my family. At times, solo trips make me feel slightly guilty. I can't help thinking about how much my family would enjoy this or that. But I still manage to enjoy myself. Plus, the family gets to experience the parks on our family trips. I'm not going to feel guilty enough to sit in a hotel room doing nothing when there are theme parks in the neighborhood.
