We are ordering Congratulation balloons and some snack goodies for our DS's gradudation from the WDW florist.
We will ask for our OWN design - 2 Congratualtion mylar balloons attached to Mickey's Kool Snack ($30 plus cost of balloons).
Our DD gets the same Mickey's Kool Snack with Happy Birthday balloons.
We have 2 celebrations the week we go. DS graduates the week before we leave and DD's birthday is 2 days before we leave.

I also went to our local
Disney Store and found a graduation Mickey (colors blue & gold - My DS's actual school colors

).
I am going to bring the Grad Mickey to WDW with us and present it to our DS with a card - not sure where yet - maybe Coral Reef - his favorite place to eat. I am not sure if Coral Reef can do a 'Happy Graduation" dessert - but we can create our own magic
Our DD will get her WDW birthday dinner at 1900 Park Faire. They give the birthday girl a tiara and we are ordering her for dessert the small white cake with white butter cream frosting and a white chocolate castle on top.
1900 Park Faire may be able to also give your Graduation DD the tiara and do a small special dessert for her. Ask for the table to be decorated with Mickey/Minnie head confetti.
