We love receiving your questions! I especially love your enthusiasm! You can definitely ship a box ahead of your trip! I would probably send it a few weeks before to allow for transit time. Be sure to address your box with your reservation number, the name of the main person on your reservation, and the arrival date. Here is the address and phone number:
Lake Buena Vista, Florida 32830-8423
(407) 824-2000
I highly recommend that you get tracking services so that you can confirm delivery. When you arrive at the resort, just stop by the concierge desk and they will be able to retrieve that package for you!
It has been a pleasure assisting you! Please be sure to send me any other questions you may have!
Thanks for sending your question to the Disney Parks Moms Panel!
