Hi Sam,
You are going to love it at Disney's Yacht Club Resort - I stayed there during my Moms Panel training trip and thought that it was fabulous!
The best way to purchase tickets for Mickey's Not-So-Scary Halloween Party from the UK is via the Walt Disney World website Ticket Store. You can access this by clicking on the
Buy Tickets Now! button which is located on the Mickey's Not-So-Scary Halloween Party page.
If you choose the Disney eTicket delivery option, your tickets are immediately available and can be printed on your
computer at home. (This option is only available if all of the tickets in your
order are for a Special Event.) Tickets for the 2014 parties will most likely go on sale around the beginning of May 2014.
Although I have never done it myself, I do believe that you can order
Disney Dollars ahead of time by calling 001 407 566 4985, pressing Option 5 and using a credit card payment. Disney Dollars ordered with a credit card are limited to $50 per day, and a shipping charge will apply.
It is also possible to pay by cashier's check or money order, by mailing your payment and order
information to: P.O. Box 10140, Lake Buena Vista, FL 32830. Please note that there is a maximum order total of $650, and a shipping charge will apply.
My best advice to you would be to get US Dollars as gifts for your girls which could be converted to either a Disney Gift Card or
Disney Dollars on your arrival at Walt Disney World.
Wishing you a magical trip filled with memories which will last a lifetime!
