For some reason I don’t understand, my grandmother never actually celebrated her birthday on her ACTUAL birthday. Instead, she had an “alternate” birth date that she’d been using since she was young.
Thing is, her license still showed her ACTUAL birthday. This was fine, until it came time to receive the age percent off discount on your birthday AND a free birthday cake at Bill Knapp’s. So, every year, she had to convince the wait staff that for HER, her birthday celebration day was, in fact, the day she ALWAYS celebrated her birthday. In other words, she wouldn’t be at Bill Knapp’s on her ACTUAL birthday…or if she was, she wouldn’t ask for the birthday discount.
In the end, they relented, and gave her discount and free cake. (I suppose it was helpful that there were usually about 5 to 10 other people there as well.)
Point is, if Bill Knapp’s considers it morally acceptable, I see no reason Disney wouldn’t.
Of course, having said that, Bill Knapp’s eventually went out of business. So there’s that.
(I really should ask my mother WHY her mother decided to celebrate her birthday on a day OTHER than her actual birthday. Unless you are born on Feb. 29, which she wasn’t, I don’t see a reason for it!)
