Hi Kerri,
Thanks for your question. You must be so excited for your upcoming vacation!
Guest Relations windows are open during theme park hours at each theme park. So check the hours of the day you plan to visit for the correct times to arrive. They also tend to be open a little earlier and a little later than stated so if it were me, I would plan to arrive an hour or so before the park opens to make the most of my time.
It is my understanding that tickets may be picked up at each of the theme parks as well as the Disney Springs Guest Relations window. You'll find a Guest Relations window either in The Marketplace or at
DisneyQuest Indoor Interactive Theme Park. If you plan to arrive in the evening, I would head to
Disney Springs before I would check a Resort. Once you have your ticket, you'll love walking around checking out all the incredible new shops and dining options!
I hope this helps you plan for your magical vacation, Kerri. Please let us know if you have any other questions.
Enjoy your trip!
Andrea U.
