I think that California Adventure would be fun to see first, then Disneyland. Hit TOT, California Screamin', and Soarin' over California first thing. Then hit DL. If you hit DL first go to IJA or Tomorrowland first. If you go to IJA ride that, then head over to critter country and ride SPL Mtn, then Winnie the Pooh, Haunted Mansion, and Pirates. After that begin to use the FP, as you work your way to Tomorrowland. Hit Big thunder Mountain, forget Fantasyland, unless you have kids. Walk over and ride the MAtterhorn, then Autoipa. Finally finish off with Space Mountain and Star tours. Beware Star tours is a lot more popular in DL than WDW. Also Space mountain is not as bad as WDW.
The other plan is hit Tomorrowland first. Ride in this order, Sp Mtn, ST, autopia. Hit Matterhorn and walk over to IJA. Get a Fp and see tiki room. Ride IJA then go to critter country, hit sp mtn, WTP, HM, and pirates. Finish off with big thunder at night (oh yeah). Toontown is a toss up, I have been to DL many times, like 30 or more times. Anyway you might or might not go. The only big themed ride is Rodger Rabbit Cartoon Spin, where you ride through the movie, in the cab. and you can spin the car by turning the driving wheel. So it doesn't matter. And I chose not to mention IASWAA, (its a small world after all) because it gets on my nerves.
