When does Disney start announcing prices for the next year? (2012)?

The others are right. Announcements are generally in August. But, if you every plan on going to Disney world again in the future I would suggest that you buy your park tickets now and purchase as many as you can afford with the hopper and non-expiring option. I bought a 10 pass several years ago and use two days a year (I've been there so often that I can get through everything in all 4 parks in just two days). It's great to know that I'm still traveling on 2008 prices!

disney world announces any price changes and opens bookings for the next year in mid august.

Nope. the guy is and has consistently been clean. this is a shame that suspicion has to fall on somebody because of the fact of their extreme ability point. yet in those cases... i actually do no longer see an benefit to drug use in golfing. And at present, Tiger is lower back with the %. for long drives. this is each and every element of his interest, from tee to green that makes him so good. no longer dope. yet, no.

Historically, sometime in August. Sometimes it is early, sometimes it is late, just depends. But that is when they have released prices the last several years. You can go ahead and book by calling, if you want to.
