Welcome BACK, Luciana!
I'm so excited that you're coming back HOME! So many
new experiences, attractions and snacks have been introduced since your last visit, with many
more upcoming additions announced just this last week.
I was in your shoes this time last year when I was planning a magical Walt Disney World Resort vacation for my own family. We were within our 180 dining reservation booking window, but I could not find space in any of the dessert parties. Through my time on the Disney Parks Moms Panel, I've learned that
Dessert and Dining Events open their own calendars at their own time frame; some only take bookings 45 days in advance while some go out 120 days. Others will open up an entire month at a time once the first day of said month is so many days away, and I *think* that's what might be going on with the
Celebration at the Top - Savor, Sip, and Sparkle fine food and fireworks dining and dessert party.
While I don't have the proper Magic Mirror to see when your desired dates will open up for bookings, given that we can see party dates through the end of December right now, I would think that you should be able to make your February 2019 reservation by November 1 of this year. If the February calendar is still unavailable for online bookings by November 15, I would call the Disney World Dining phone line, which is (407) 939-1947.
I hope this helped, Luciana, and We'll See You in 2019!
