Hopefully you're still gonna be able to go, Jesse! It'd suck if your days off right now with pneumonia prevented you from getting a few days off later this month...

But assuming you do still get out here, first and foremost, get together with my ass at some point. Then, regarding the actual park, you'll definitely need to hit most of the aforementioned places:
Star Tours
Indiana Jones
Pirates of the Carribean
Haunted Mansion
Those have always been my 4 favorites anyway. I guess if you don't like coasters, you can skip Space Mountain, Matterhorn, and Thunder Mountain then. What about log rides with big drops? If that's doable, then hit Splash Mountain.
For your girl, you'll have to hit Small World, without a doubt. Then wander around the various rides in Fantasy Land (Snow White, Peter Pan, Alice in Wonderland, etc.) and hit up "Toon Town" which has a LOT more kiddie stuff. I hear that new fireworks show really kicks ass too, so I suggest scoping that out (it's kinda late though - 9:30pm, I think). Your daughter will love the new parade too, so find a good spot (early) for that.
The book also stresses the importance of the fastpass as Diddly indicates.
Most definitely. A highly intelligent person can virtually eliminate the lines completely (or at least any lines longer than 10-15 minutes) by using the FastPass tickets. Whenever I go to DL, I basically just run around and
collect hoarde those FP tix everywhere. Just accumulate a whole bunch as the day goes on, and since they're good for the rest of the day (IIRC), you can go back to those rides/attractions anytime later on (after an hour) and just stand in the
very short FastPass line. The common misconception is that you can only have one FastPass ticket at a time. Screw that. Grab a ****load of 'em everywhere you go! I'm always amazed at the stupid people standing in the monster lines for a good hour or two, when I can just walk up to all the same rides and hop in the 5-10 minute FastPass line. Duh...

Keep us posted on your travel plans, Jess! Good luck on making it out here...
