Hey there, Chris!
I am thrilled to hear that you are coming down to sunny Florida to experience The World's Most Magical Celebration!
I just booked a few
advanced dining reservations myself, including a reservation at the brand-new
Space 220 restaurant in EPCOT!
Chris, reservations generally open at 6:00 am Eastern time; however, a few locations begin accepting reservations at 5:45 am Eastern time.
I recommend that you start making your advanced dining reservations around 5:45 am 60-days out. If you are staying in the Disney Resorts Collection, you will be able to make reservations for your entire stay 60-days in advance of your check-in date. Otherwise, you must log in 60-days before you wish to dine.
I also find that I have better luck making dining reservations online versus through the
My Disney Experience Mobile App.
I hope that this helped, Chris!
Good luck!
Sarah B.
