Hi Andrew!
Welcome to planDisney.
It's always a pleasure to assist my fellow guests from the UK, and I would like to help you purchase your Date-based Multi-day tickets, but unfortunately we cannot access the US site (www.disneyworld.disney.go.com) from the UK, and I know how frustrating this is because I encounter the same issues myself.
Currently, the only way for you to purchase these tickets will be once you have arrived in the United States when you can visit 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 arrive in the US you can buy your ticket online.
I recommend you consider buying our
UK 7-Day or 14-Day Magic Tickets because they offer great value compared to single-day tickets purchased in the United States. Our Magic Tickets include park hopping, entry to the Disney water parks (Disney's Typhoon Lagoon and Disney's Blizzard Beach, subject to whichever is open), and
Memory Maker giving you unlimited digital downloads of PhotoPass photos of you and your family, while in the parks and on some of the attractions. For tickets purchased in the United States there is an additional charge for water parks and Memory Maker. If you would like to know the current ticket prices in US$,
please send me a direct question, with your travel dates, and I can research those for you so you can make a price comparison.
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.
Sue
