I believe WOC FP'S should hold out until early afternoon at least.
I would go for Carsland and RSR first thing. A popular strategy is to ride stand by and then get your FP'S afterwards for a later ride. RSR at night is super awesome, actually I like all of Carsland better at night!
Flo's V8 Cafe has a pretty good size breakfast menu, but elsewhere in DCA is pretty sparse. I'd try Flo's for breakfast and then head towards the WOC FP distribution spot at Grizzly River Run, and grab FP'S for Soarin or Grizzly on the way.
Have fun!! Wish I was there!!
