"There are no errors on the schedule and what you see linked is exactly whats available internally. Mickeys Jammin Jungle Parade is expected to end in June around the same time as the Festival of the Lion King theater in Africa opens. That has not been formally announced and the Parade will continue to be listed until an end date is confirmed. Likewise, Disney has not announced the start date of the new Festival of Fantasy Parade, even though its widely speculated to be in the middle of March. Festival of Fantasy should certainly be running in September, but Disney wont add it to an official operating schedule until the start date is formally announced.
There were a few questions about two evening Extra Magic Hours on Mondays with the addition of Mickeys Not So Scary Halloween Party on Sundays. The bottom line is that Disney is trying to sell as many tickets to those Parties as possible. With no Extra Magic Hours scheduled on Sundays, people are more likely to purchase tickets. If Disney moved the Studios evening EMH to Sunday and kept the Park open until 10pm, they would sell fewer tickets. I would not expect the Extra Magic Hours schedule to change unless they decide not to run the Halloween Party on Sundays. Remember that Halloween Party dates are not finalized and they have shifted in the past.
There are always questions regarding the initial release of an operating schedule as people compare the operating hours to last year. You can take a look at least years final schedule here. Disney always releases a conservative operating schedule first and then follows with an update closer to the start of the month. Before MyMagic+, those updates usually came just 2.5 weeks before the start of the month. Now they come about 3.5 months in advance. Look for a major update to Septembers operating schedule around May 16th. The final schedule should look more or less the same as last year.
The recommendations are otherwise mostly what you would expect. Animal Kingdom comes tentatively recommended on Mondays even with the morning Extra Magic Hours attached because Magic Kingdom and Hollywood Studios will be so popular with evening EMH. Epcot is also tentatively recommended on Tuesdays during the Food and Wine Festival because it isnt much more crowded than the recommended Mondays and Thursdays and is far less crowded than the weekends. Ideally, only people eligible for EMH that plan to arrive in time to take advantage of it would visit on those tentatively recommended days, but theyre not so bad that they come not recommended."
