Hi, Sandra!
That certainly is a fun tradition you have started. Your son must get so excited for your vacations!
When packages are delivered to your resort, you will be notified and will have to pick them up yourself, usually at the front desk. I have not seen packages delivered directly to your room. However, I suggest you contact your resort concierge desk and ask for options or ideas. Hopefully they can give you some suggestions on ways that guests have been surprised in the past with magical gifts.
Disney Floral and Gifts is always updating their inventory, so make sure to check them out to see what they have created. You may also want to browse around the
Disney Store online for idea. A super easy option is to customize
Disney Gift Card for your son. This will be an easy gift to take with you, and can quickly display when you enter your resort room. Plus, it is a gift that keeps giving since he can then go shopping!
I hope you find a great way to surprise your little prince on your upcoming Walt Disney World vacation!
Cathy
