Hi Emily, welcome to planDisney! I am so excited you have a trip to the Most Magical Place on Earth on the horizon!
From your message, I believe that you have booked your reservation directly with
Walt Disney World Travel Company and that your mother has previously set up a
My Disney Experience Account. If so, and she has forgotten her password, simply click on 'Need help signing in?' and follow the steps to access her My Disney Experience Account.
To add a
Disney Resort hotel to your booking, click on the 'Link a Reservation' on the Resort Hotel tab in My Disney Experience. The confirmation email sent to the lead passenger (whoever made the booking) will include a unique code confirmation code that will need to be entered along with the surname of the passenger. If you do not know the number, please call the
Disney Experts in the UK. From experience, it will need to be the lead passenger that makes the call. Once you have added the Disney Resort hotel to the booking, you can link any relevant Guests already added to your My Disney Experience.
Please remember that British nationals travelling to the U.S.A. under the Visa Waiver Programme must apply online via the Electronic System for Travel Authorization (ESTA) at least 72 hours before departure.
Emily, I hope this information was helpful, and I will be right here if you need anything further, Louise
