Hi Debby!
Welcome to the Disney Parks Moms Panel. Birthdays spent at Walt Disney World are always extra special. Be sure to pick up your daughter a "Happy Birthday" button when you check-in. This cute button is free and will get her lots of smiles and well wishes sent her way on your trip. They also make for adorable souvenirs.
Debby, the only people who will be allowed to access your room would be Disney employees such as housekeeping, maintenance and
Disney Floral and Gifts. Outside vendors and non-Disney employees will not be able to gain access to your room to decorate. Disney Floral and Gifts offers many adorable
In-Room Celebrations that would be precious ways to surprise your daughter on her big day. I have used their services on many of my vacations and my children always love the adorable gifts waiting for them when they got back to the Resort after a fun day in the Theme Parks.
Outside Vendors do make gift baskets that can be delivered and left at the front desk of most Disney Resort hotels. Just search online for Disney Gift Basket deliveries. The basket wouldn't be in the room but she could pick it up at the front desk.
I hope this has helped answer your question, Debby. Please pop in again anytime you think of another question you may have about your magical birthday adventure. It's always fun to lend a helping hand to fellow Guests.
Dream as Dreamers Do,
Jen
