Hello Sharon,
Welcome to the Disney Parks Moms Panel! You may Check-In at any
Walt Disney World Resort Hotel, Cabin, Campsite, or Villa upon your arrival, no matter how late that may be. Cast Members are available at all hours to assist Guests with their Resort Check-In.
Since you know that you will be arriving at a late hour, I suggest doing Disney's
Online Check-In ahead of time. It will expedite the process once you arrive at your Resort. You can check-in online (at select Resort Hotels) 60 days prior to your stay. Once you have arrived at your Resort head straight to the Online Check-In Desk, show a valid photo I.D., and then faster than you can say "Supercalifragilisticexpialidocious", you'll be on your way!
Please stop back by if you have any additional vacation planning questions!
Magical Wishes,
Susan
