Pricing has been published by multiple sources. The Orange County Register, a paper local to the area, noted:
"The three-day, one-park per day tickets start at $149 for children and $249 for adults for admission Monday through Thursdays. That works out to just under $50 per day for kids and $83 a day for adults.
You can also get weekend three-day, one-park tickets good on Fridays, Saturdays and Sundays for $199 for kids and $299 for adults. That’s $67 a day for children and $100 for adults."
The first part of that information had already been published by Disney. Numerous fan sites and blogs and news sources have been reporting the second bit of information. All of these prices match last year's offer, so I expect what is being reported is accurate.
Park-hopping on 3-day tickets is an additional $70 total. Pre-purchase of
Genie+ on 3-day tickets is an additional $90 total. I do not expect Disney to offer further discounts on these add-ons, and there have been no rumors or reports to suggest they will.
As for what time the tickets will be released, sorry I can't help you there. Special event ticket sales lately have started no earlier than 9AM PT. Dining reservations often go live at 6AM PT. Could be one of those times or a different time altogether, random or chosen internally by Disney.
