When I made reservations and they asked how old I said well she is 7 now but she turns 8 while we are there, not knowing they would do anything, and she asked me what date so I told her. When we checked in the CM said to her I see you have a birthday this week, I still didn't think anything would happen. Well when we got back to the room on the night of her birthday she had a little birthday cake there with a card from Mickey! We were all sooo surprised! So if you didn't mention it when you made reservations you definitly want to bring it up when you check in.
