I was solo for the first half of a trip last year at WDW. It was a little weird at first, but I very quickly realized I could do ANYTHING I wanted without answering to a blessed soul

, and I could eat when I wanted, and there was no worrying whether someone else was having a good time.
One thing I did on my own that I loved was to take my time exploring the Boardwalk and Downtown Disney!
I really like CBR and AK--have never stayed at WL, but that's coming soon.
The only real planning I recommend is ADRs, so it's a good idea to have a general idea of where you want to be, and when. The rest you can play by ear--that was the most fun for me, as I am usually a hard core planner!
If you're wanting a dinner where you can really soak in some really wonderful atmosphere, try Jiko. I had a wonderful dinner there, and tried a really nice wine. It's a beautiful restaurant. I also rec. Artist Point also for the atmosphere (wonderful cedar plank salmon) and Narcoosee's (for the fireworks!)

If you want fun and interaction, try 50's Prime Time Cafe. The food is down home, and the interaction is hilarious--being solo, you will most likely need to let them know ahead of time that you want the interaction, so be SURE to ask for a server who is in character, and let them know you're there for the fun.
Finally, I also rec. letting the CM making your ADR's know that you're solo--they will most likely have some great ideas.
I'm kind of wishing I had some time to myself on our upcoming trip! LOL
Have a wonderful vacation!!!
