Hello Colleen!
A big HAPPY BIRTHDAY to your daughter and what better place to celebrate than Walt Disney World! Room assignments are not finalized until you have checked in at your Disney Resort, so there is no way to know what room number you will have ahead of time. Although there are a couple of options that you could try so your daughter can receive her birthday gift on your arrival day.
Guests often mail packages to their Disney Resort ahead of their arrival, you could mail your daughters present to your resort and it will be waiting for you upon check-in and have the cast member present her with her present. When sending a package to your resort, make sure to put your name and reservation number in the c/o line. I would also recommend using a red sharpie to write "GUEST" and your reservation number on the package itself to make sure that it is not mixed up accidentally. If you prefer to have the delivered to your room, you could also leave the package along with your luggage and have bell services deliver them to your room. Someone will need to be present in order to receive the luggage and package.
If you are having a gift delivered by
Disney Floral & Gifts, they will set up a block of time to leave the special surprise in your room. They generally do not make any deliveries on guests arrival day, since they will need confirmation of your room number. I hope this helps and please visit us again if you have anymore questions!
Enjoy your Disney Time!
