Trust me. Almost everywhere is booked. As of this weekend, the only available restaurants in the WD for T-day were Norway, China and Germany.
The only resort restaurant that was available was 'Ohana.
Spoodle's had some availability, and Palio's.
The times for PS were quite late.
If you've not made a PS by now, you are really going to need to be flexible and most likely prefer dining late.
