I was raised on WDW and only discovered DL as an adult when I moved to L.A. right after getting married. I adore both locations (see my quote to the left!) and I firmly believe that anyone who is a Walt Disney fan owes it to themselves to make at least ONE visit to DL.
I will predict (Tom, I'd love to hear your thoughts on this) that FP+ will not come to DL. DL has a much larger base of locals to contend with than WDW does. A LOT of people wake up, rub their eyes, yawn, and say, "Hey, let's go to Disneyland today." FP+ would not work for them and it would probably make them angry. And like I said, I know that WDW has locals with AP's, but DL has a lot MORE of them.
