Hi, Joanne!
What a lovely idea! How exciting!
I spoke with a Cast Member from Disney Floral & Gifts who told me that you could customize in-room celebrations in several ways. For example, if you order
Presenting Your Royal Princess-Junior, you can request that the proclamation which declares that your daughter is a royal Princess (usually signed by the Fairy Godmother) to be signed by Belle, instead. Then, you can add a
Princess Balloon Bouquet to the package (Snow White featured in the link above) which can be customized toward Belle, too. Even better, the weight that holds the balloons down is a collectable princess doll, in this case, Belle!
Call Disney Floral at (407) WDW-GIFT (407-939-4438) and speak with a Cast Member about other celebration ideas as well.
Your princess is sure to know how very proud you are of her 8th grade graduation with such carefully-planned details, Joanne. Enjoy the moment...they grow up so quickly!
Send more questions as you think of them; we love to help Guests celebrate!
