We will be in Disney the week before my DD 3rd birthday, so I was thinking of having her a little birthday party there (cake, get the birthday pin, ect) but I also have a DD8 who will never see Disney on her birthday due to school (She's a Dec baby) and I don't want her to be upset that her sister gets to have the Disney birthday experience and she doesn't. So I was wondering if it would be innappropriate to let her celebrate her half birthday along with her sister at Disney? Her half birthday would be in June so it wouldn't be to far out from our vacation time at the end of May. This is actually something I have been thinking about doing for her every year since her b'day is right before Christmas and it makes it hard to celebrate it on her real birthday, and we would be able to have a better party for her than we can right before Christmas. What do you think?
