First of all FLYING INTO FORT WAYNE DO NOT FLY INTO LAX!
I have been to both WDW and Disneyland several times, and I love them both. As my 1st experience was with Disneyland I am a little partial to the original though. There is a HUGE difference between WDW and Disneyland. First Disneyland is so compressed, Main Street USA is much smaller at Disneyland then at Disney World, Pirates feels so crammed into New Orleans Square, and well everything feels a little crammed which it is. I also personally think the Haunted Mansion and Pirates are also quite a bit better at Disneyland then at the world. (Pirates has two drops which are both a little larger then WDW and tells the story better)
Also as people have already said its all walkable, but unlike Disney World, while there IS on property its not like on property at the World, the real world is viewable from pretty much everywhere. Or there is no "you are now on disney property" feeling unless you are either in the hotel, or in a park. Make no mistake the Disney Magic is there its just different.
How Disneyland Resort is laid out is that there is the parking garage (or parking structure
as they say on the trams) on one end, that leads into Downtown Disney, which leads to the esplande, a large plaza area between Disneyland and California Adventure. If you have been to Universal Resort in Florida its pretty similar in layout, and walking distances. (parking garage, City Walk, Universal Studios on one side, and IOA on the other).
At Disneyland on property is not like on property at the world, but the last time I was there we did stay at Grand Californian, we are trying to go in January and will probably be staying at the Paradise Pier. I checked mousesavers and it looks like a good discounted room there is about $109, I am hoping to get something around that rate. I still like staying at Disney because I feel like I know what Im getting, you still get package delivery, and well its Disney!
Be careful is you do decide to get an annual pass, while AP's still get you good discounts at the hotels, there are two types, one that includes several black out dates, make sure you know which one you are getting.
Also last time we where there we stayed 3 days, I think that's what we will be doing again, it seems like a good amount of time to see everything at a relaxed pace. I am also hoping to get to see the Main Street Electric Light Parade again, I hope that's still at California Adventure. Its old and a little cheesy but I love it
