Add me to the list of people waiting for- you guessed it- October 7th, studio, anywhere. I was on a waitlist for the 8th and the 11th, too, but those came through already, so I'm booked for the 4-6, and 8-12 at SSR. This was a "spur of the moment/meeting friends/can't wait 18 months between WDW trips/new home purchase stress is really getting to me" vacation. I didn't know it was Columbus Day weekend, and I booked my flight first (little lack of foresight there, I know). I have a room booked at Pop Century for the 7th just in case the wait list doesn't come through. If I have to move, I'll just plan on packing an overnight bag for my one night at Pop. If I had kids, this kind of flexibility would probably not be possible, but for a solo, it's a minor inconvenience.
I'll plan better for the next trip. I already know it's going to be November, 2008, so you can bet I'm booking 11 months out.
And man, I hope that one of my friends doesn't see this. Her husband and I are trying to surprise her for her birthday. I know he reads the boards, but I don't know if she does. If you see this, Amy: These aren't the droids you're looking for. Move along.
