I have never gone completely solo but have had solo time. When my daughter sang with her choir during magical music days, I flew down to see her sing. while they were involved in musical activities I was able to spend time by myself in the parks. They also drove down on a bus (24 hour drive) and since we left at the same time and I flew there and back, I had a day by myself before they got there and a night and day after they left. I stayed a POP (they stayed outside the parks) and always felt safe. Cast Members were great during my solo times.Took an interest in me and made sure I was having a great time. I always carried a paperback so when I ate by myself it wasn't awkward (I do this at home too). This took place during the AP premier for Soaring so I was able to do the premier and met so many great AP holders in line that I never felt out of place. The only thing I felt bad about was that my daughter wasn't able to do Soaring with me and that I wasn't able to share the experience with her, but she got to do it the next time we went. THe great thing is that you get to do what you want to do when you want to do it. There is no way my daughter would have really wanted to see the late Davy Jones of the Monkees perform at Epcot, but I was able to go see him and I didn't wait in the long line, but because I was solo, I went in at the last minute, walked down to the front and people had no problem moving over a little bit just to make room for me in the front row. Got to watch parades she doesn't like to see, and go to different things she isn't that fond of like The Hall of Presidents.
We used to go about 3-4 times a year, but since my daughter is now 26, she want's to go other places, and does with her friends. (although the last two times we went, if I throw in a trip to the beach she is good) So I have been contemplating a solo trip as this is the longest I have gone without a disney trip...2 years. Let us know how your trip goes so for those of us who are contemplating solo trips as well (altho my daughter's boyfriend who did the Disney College Intern program 10 years ago is dying to go back, so my daughter suggested the two of us go together lol).
