It sounds insane. However, if Disney's timeline for SWL is progressive, they may already have their increases mapped out, and this is the first of a strategy they're implementing. Disney World Prices are up already, but we won't know how much until the site comes back online.
Twitter rumors so far:
$20 Parking at both resorts (Disney World CONFIRMED, signs are out at the lots there)
Socal Passes (both kinds) are being phased out. They are not available for renewal - once your pass is up, it's up!
Deluxe Passes - $50 increase and more blockout dates.
Premium Pass being split into Signature, and Signature Plus.
Signature rumored to be $849(ish) and will be blocked out only from Christmas to New Years.
Signature Plus will be $1049 and have no blockouts, and will also include Photopass+ for the duration of the pass.
