Awesome.
First thing I would recommend picking up a FP for is Radiator Springs Racers. People line up for those machines before the park even opens and it does get pretty long. You'll be able to fly by the longest line in DCA with a FP for RSR and knock out everything else in which the waits shouldn't be too long that early in the morning. I would definitely head to TSMM as that will be the second longest line in DCA. What I usually do if you
really wanted to crunch in as many rides as possible is have one of you wait in the FP line for RSR (which does go pretty fast) and have one of you in front of the rope. One of you would get the FP for RSR and one of you would head straight to TSMM and stand in line and eventually meet up at TSMM. TSMM in DCA does not have FP unlike in WDW.
Great FP's to pick up in DL would be Indiana Jones, Space Mountain, BTMRR, and Splash Mountain.
Most other rides lines should move pretty efficiently depending no how crowded it is going to be. Lines are lowest in the early morning before all the locals come in the afternoon/night time.
Either way you'll have a blast
