Hi Laura.
Payments on your Walt Disney World vacation package can be made online through the
My Disney Vacation tab once you've signed into your reservation at the waltdisneyworld.com website.
Payment of the full balance is due in full no more than 45 days prior to your arrival date and there are no extensions able to be made that I am aware of.
You do have the option of making multiple payments online, on multiple dates up to and including January 26th if that is the date indicated in your booking. Can can also use multiple forms of payment as indicated on the payment screen online and others can even authorize the use of their credit card to make a payment on your behalf if applicable.
The alternate option to paying online by credit card is to send a draft or money order in US funds payable to 'Walt Disney Travel Co.' which you can purchase at any Canadian Banking Institution for a minimal processing fee & the daily exchange rate to purchase US funds from your Canadian account. If you would rather mail your payment, I would recommend that you do so at least 7-10 business days prior to your due date to allow sufficient travel time through the mail system.
Payment should be mailed from Canada to:
Walt Disney Travel Co. Inc.
P.O. Box 409668
Atlanta, GA 30384-9668 USA
A full listing of booking
Terms & Conditions can be viewed through the Walt Disney World website.
I hope this helps you out Laura. Feel free to respond or contact me again through the Moms Panel site if I can be of further assistance to you.
Wishing you a Magical vacation!
Kirsten
