There are
RUMORS that they are considering raising the rates more than usual (per Al Lutz, at least, though in fairness he has been saying they SHOULD significantly raise the rates for probably 5+ years!).
Logically, they MIGHT raise the lower priced APs, such as the Southern California ones, more than they'll raise the higher-priced (Deluxe and Premium) APs. When a Southern California resident can buy a decent annual pass for less money than an out-of-towner has to spend for 3 days' admission, it does seem a little out of whack to me.
Even if there is a somewhat large increase, odds are that the Deluxe AP (is that what you're going for?) will probably still make financial sense if you are planning even one additional trip to
Disneyland before it expires. I'm wishing you luck!
