We don't find LAX particularly confusing. It's not the nicest airport I've been in, but we've never gotten lost. The way to baggage claim is very clearly marked, as are the gates. Security can be hectic depending on the time and day, but nothing worse than I've seen at other airports.
I'm also a fan of DK Livery, and will add that they'll do a free grocery stop on the way to your hotel, which comes in very handy. Also, it has the benefit of not needing to find a shuttle, because their driver will meet you at the baggage claim. Heck, a couple years ago, we were a little slow to get to bagage claim, and by the time we got there, the driver was standing next to one of our suitcases! He was waiting for us, and recognized my name on the luggage tag as it passed by, so went ahead and pulled it off for me!
One thing I will advise against is renting a car, unless you're sure you'll need it during your
Disneyland trip. Picking up a car from one of the rental agencies around LAX can take a very long time, plus you have to deal with finding your way back and forth, AND you will likely end up paying to park it if your hotel is anywhere near Disneyland.
