Is it unheard of for a single person to participate in the DVC?
I am a single person and I bought DVC. At first I purchased enough points to go every other/3 years, then I realized that I would have also liked to share it with family and friends, so I added on to get enough points to go every year in a studio, or every 2/3 years in a two bedroom, so if I want I can skip one year and book bigger rooms.
Until some time ago I did never go to a theme park alone. Then I had the chance to make some business trip to places where I could add a week end stay on my own and visit a theme park. While the experience is different, I enjoyed it. So now if I can I go with others, but if I can only be alone, I go anyway.
Have you ever gone to a solo trip to a Disney Park? If so and you enjoyed it, DVC might be an option. While bigger rooms are for families, there are studios that are cheaper in points and ideal for a single (for example, almost all have a bed and a sofa instead of two beds like most of hotel rooms).
Reading your post, I can see that you don't know DVC, so I recommend to read this boards for a few months before purchasing. There are a lot things to fully understand the program and it's a costly purchase, so it's better if you know if it's really for you (because it's not for everyone).
