Head into Critter Country first, to get a Fastpass for Splash Mountain, as those sell out very early in the summer. While waiting for that time to roll around, head over to Adventureland and ride Indy before Stand-by gets too unbearable.
Ride all of the Fantasyland rides in the morning. Large crowds do not show up in the summer until the afternoon, and since Fantasyland is Fastpass-free, get on those rides before they all have 40 minute waits.
See Remember at 9:25 and then sneak over for the 2nd showing of Fantasmic!, which is less busy.
At DCA, start off w/ a FP to Soarin' and Grizzly. Grizzly is on a separate FP system, so you can get a FP for it and any other DCA FP attraction at the same time! The same can be said for Roger Rabbit's Car Toon Spin at DL. While waiting for your DCA FPes, go ride the ToT. Pretty much the only MUST SEE in Paradise Pier is California Screamin', which is much better at night.
