I'm hopeful that Magic Kingdom will show Fantasy in the Sky at both 6:30 and 11:50 on the 30th and 31st as they have in years past. I've gone for New Year's in 2017, 2018 and 2019 and have enjoyed 4 showtimes for Fantasy in the Sky on each trip. I feel fairly certain that New Years fireworks will be shown at midnight at both MK and Epcot, despite what the calendar shows at this time. If there are no New Year's fireworks at Disney World this year, I would probably cancel the top-dollar NYE trip I have planned. (Extremely high
ticket prices and room rates, with no discounts offered.) As far as the early fireworks shows... it's possible that they'd leave the "regular" Enchantment and Harmonious shows. If so, that would be a big change from past years, and a big disappointment for me.
