On my daughter's 6th birthday we ate at the crystal palace (her favorite) the cast members made it very special, gave her a cupcake with a candle & sang happy birthday. I just let them know we were celebrating her birthday. You could also order a cake in advance & have them serve it. - perdita  64.9 #63 11:04AM

Don't forget to remind them at your hotel desk. They are good about remembering usually, But remind them and there will be at least card there for him when you arrive back to the room. Wear h is birthday button on him and he will get many happy birthdays through the day. No matter where you decide to dine you can request some kind of desert. Last year we did birthday at trex and orders the lava cake and it comes out smoking and these frills on it an tastes amazing. We all shared. It will be a fun trip for you. Have a great time - mmddgp  187.4 #26 11:32AM

Just put it in your dining reservations. I did that for ours, and they brought out something for the b-day person at our dining. You could also call dining and ask about a cake being delivered to the table. - Lelundrial  344.9 #435 12:06PM

Are you certain that it is all booked up? The Dessert party ressies don't open until roughly 60-65 days out. They just may not be open yet. Also they only do it on certain nights, not every night. I would keep checking. I think you will be able to get it. - poohbr1205  14.3 #157 10:41AM
