Hi Emma! Welcome back to the Disney Parks Moms Panel!
Great minds must think alike because I, too, booked the
Fantasmic! Dessert and VIP Viewing Experience for my upcoming trip that is just a few weeks before you family visits. I don't know about you, but from looking at the gorgeous picture of the yummy snack box, I don't know which treat i'm more excited about!
I also ran into the same problems during the booking process that you are having, and I think it boils down to this: traditional sit down dining reservations can be made up to 180 days in advance, but special events that have separate tickets, such as dessert parties, are usually bookable around the 90 day mark. Sometimes it's 90 days to the day, and sometimes the whole month opens once the first day of the month is 90 days out.
Try again with your specific dates now that you're in that 90 day window, and if you're still unable to reserve the
Fantasmic! Dessert and VIP Viewing Experience online, please don't hesitate to call the
dining reservation line.
Thank you so much for reaching out to the Disney Parks Moms Panel, Emma, and I hope that you and your family enjoy Fantasmic! (And those treat boxes.)
