Well hello there, Rebecca. It's so nice to virtually meet you and answer your question!
At this time, Guests from the United Kingdom and Ireland can only purchase either a
7-Day Magic Ticket or a 14-Day Magic Ticket ahead of their arrival in the United States. That being said, you usually do not have to wait until you have actually arrived at the
Walt Disney World Resort to make your 1-day theme park ticket purchase. Once you have
landed in the United States, you should have access to the United States version of the website and the ability to purchase a 1-day theme park ticket!
While this may not be the news you'd like to hear and theme park tickets
are always subject to availability, they don't sell out very often. This usually only happens on or around holidays. I know this isn't the guarantee you might be looking for, but you can also keep an eye on the
Theme Park Reservation Availability Calendar leading up to your arrival. Since you are likely purchasing a date-based ticket, you probably won't require a
Theme Park Reservation, but this calendar may give you an idea of availability as your arrival date approaches.
Rebecca, I wish you a magical day at the Most Magical Place on Earth. Should you have any other questions, you can always
reach out directly to me.
Let love guide your actions,
Matt
