Hi Judi!
Welcome to planDisney.
It's always a pleasure to assist fellow guests from the UK especially with questions about park tickets as I know it can be confusing.
Currently, the only way for you to purchase a single-day ticket for Magic Kingdom Park will be once you have arrived in the United States at a Ticket Window at any Disney theme park or water park. If you are planning to visit
Disney Springs on your first day or so, you can also buy tickets at the Ticket Center there. Alternatively, once you set foot in the US you can buy your ticket online.
For Guests in the UK, we can purchase
7 or 14-Day Magic Tickets which offer great value compared to single-day tickets purchased in the United States (more on those later). Our Magic Tickets include park hopping, entry to the
Disney water parks (Typhoon Lagoon and Blizzard Beach, subject to whichever is open), and Memory Maker giving you unlimited digital downloads of PhotoPass photos of you and your companions, while in the parks and on some of the attractions. If you will be visiting Disney theme parks for 3 days or more, these UK-exclusive tickets offer you the best value for money, when compared to buying single-day tickets (which present an additional cost when adding on park hopping, water parks, and Memory Maker).
Please come back and visit us if you have any further questions. We will be happy to help you plan your magical holiday, and keep your eye on the
Disney Parks Blog for all the latest official news about events that may be happening during your stay.
