Yep, what everyone else said!
Key to good days, IMO, is to get early starts at DL. Then when you want to, go over to DCA.
Though i do have to say, I enjoy opening up DCA too, which generally (for us) means being at the gates of DCA sometime between 9 and 9:30, at 9:30 they'll open the gates so you can shop and ride Soarin' (and get FPs for the same ride), then get in line up at the rope waiting for the rest of the park to open. That way you can get onto TSMM a time or two before the line for it builds.
