Good question. Hopefully they won't take to long to make up their minds. My suggestion for you, which I plan to use myself because this will affect us for making PSs, is to make 2 PSs and cancel one when the hours are released. My reasoning is that I may make a ps at CP for breakfast on EE day and now I will make 2 because the EE day would change under the new perk. Same goes for dinner. Do realize though that if you were to look at the historic park hours that MK will probably be open later than what they were last year regardless. If they plan to show Wishes every night, 6 or 7pm would be too early it wouldn't be dark yet, so remember that when making your PS and other plans. I hate that Disney doesn't give advanced hours too advanced, but I am thinking of it giving me more planning opportunities!!!
