Disneyland burnout happens. It happened to me the last time I was there (course, the last time I was bummed because the high winds forced them not to have fireworks
).
Anyway, just give it a little time and you'll snap out of it. I just listened to my 50th Anniversary CD collection a few weeks ago and got all excited about wanting to go back.
Course, now that my wife is unemployed my dreams of going back to the Magic Kingdom will have to wait even longer. Ah well, absence makes the heart grow fonder, I suppose.
