Glad you had fun! I was apprehensive before my DL solo trip last fall, but it was awesome. So much so I'm doing DW solo at the end of July!
My new goals are to take more pictures (got a nice new P&S camera), and try more TS restaurants. There weren't as many "great" places to sit down at DL, so it wasn't a big deal then, but now I know there are a few places I'll try. I don't mind eating alone, but it can feel a bit weird depending on the situation.
My favorite part of being solo is just having complete control. I can stop when I want, go do this or that ride, go swim, go nap, etc. It's fun with family too, just different. I like both experiences!
