that PS now can be made 90 days in advance----however on The WDW website--the calender for hours and fireworks/parades isn't up yet. We are headed down at the end of March and nothing is posted yet. Doesn't make sense to me. Just a comment.
Well ... not EVERYONE bases their PS on fireworks and parades, you know! And, really, you can make breakfast and lunch PS without knowing about parades or fireworks. The parks are always open at lunchtime, and morning opening doesn't vary much throughout the year.
I'm with you. We had to change our PS for Fantasmic Dinner Package three times because we wanted to make sure we saw Spectro and the dates for it kept changing.
Check again. I went on the Disney website earlier today and got the hours for our March trip. It did take some searching with the new layout but it was there. Good luck!
