I've been looking all over for the Disney policy on birthdays but can't seem to find it. We're planning on going Oct 17th -27th to celebrate my daughter's third birthday (on Oct 23rd). If we check-in and begin our stay will I have to buy her a pass. It's no big deal I'd rather know because If she requires a pass anyway, we might change our plans to early Dec. to see the Christmas decorations. Any input would be great. Thanks!
