Just got back from a trip where DD celebrated her 8th bday (from 10-15 to 10/18). Definitely get a birthday button from each park's guest relations (and also Downtown Disney, too). At all our TS meals (lunch at CRT, breakfast at PSB, and Mama Melrose DD had special dessert, or special drink). Lunch at CRT was the most special. The CM waitress sprinkled the table with confetti mickeys, had a special certificate which was signed by all the princesses in addition to her autgraph book; and addition dessert of a cupcake where CMs had the room sing her Happy Birthday. At our resort (Pop Century) when checking in, I mentioned her birthday during our stay, and on 1 day we came back to the room where she was greeted to a balloon bouquet and an autographed picture from Cinderella. And once at AK, we were moved to the fast pass lane on Kilamanjaro Rapids, because a CM saw the button. Countless CMs would stop and wish her Happy Birthday. . .
