Hi Leeann!
Welcome to planDisney.
It's always a pleasure to assist my fellow guests from the UK, and with the recent changes to the Disability Access Service (DAS) I am happy to help with answering your question.
It's entirely your choice - you can register for DAS before you arrive at the parks, or when you are actually in the parks. The only specification is that you will have to wait until you arrive in the US before you can register.
Every guest who wishes to register for DAS is required to have a video chat with the DAS team up to 30 days in advance of their visit. Once you are in the United States, please
use this link to speak with a Cast Member (this will only work in the US, and you'll need to scroll down the page to find the link for a video chat).
If you want to wait until you are at the parks, you may use your own phone to have this video call, but you might be more comfortable connecting from your Resort hotel room, or another quiet private area at your hotel. You can also visit any Guest Relations at the parks where you'll find help with linking to the video chat. You can do this on the first day of your visit, or any day that suits you, in order to get everything organised for your stay.
I hope this explains what you need to do, but please come back and visit us again if you have any further questions, and you can also
send me a direct question if you wish. We will be very happy to help you plan your magical holiday to Walt Disney World.
I'm excited to see that your holiday is just around the corner, so remember to keep your eye on the
Disney Parks Blog for all the latest official news about events that may be happening during your stay. Christmas is everywhere! Enjoy the most magical time of the year!
Sue
