it can still be noted on your ADR's ~ and not be looking for freebies ~ majority of the CM's ask if you are celebrating something without any prompting from the caller.
Not to start something but why note it if you are not hoping for something? The OP just wanted to order a cake which she can do without the pain of calling and have it noted on each ADR. Edited to add that in all my years of going to WDW I've never been asked if it was a special occasion. Not that I would tell them if it were but just wondered who is getting asked this all the time from the CMs? The only thing we are asked at check in at the podiums is if there are any food allergies. LOL!
