Hi Stephanie!
Welcome back to the Disney Parks Moms Panel with a very good question!
I live in Brazil, so many times when I visit the Walt Disney World Resort I mail presents to my American friends.
Mail Services allow Guests to send and receive mail at select Disney Resort hotels during their stay.
You can mail postcards and letters from any mail box located at the theme parks or at the Front Desk of Disney Resort hotels. Postage must already be applied, and stamps are available for purchase at many gift shops, including The Newsstand at Magic Kingdom Park, Camera Center at Epcot, Oscar’s Super Service at Disney's Hollywood Studios, The Outpost and Garden Gate Gifts at Disney’s Animal Kingdom, and World of Disney at Disney Springs.
Disney’s Contemporary Resort features an onsite
Business Center so you will be able to ship packages from there. Regular shipping and handling fees will be charged.
To receive mail throughout your stay you must make sure that the letter or package includes the correct mailing address of Disney’s Contemporary Resort, and clearly features the work “Guest” before your name and date of arrival. If you plan on receiving packages, please note that a $5.00 per package handling fee will be charged for all packages received.
Thank you for stopping by once again! I hope this helps and that you have a magical visit!
