Did you want your siblings in the delivery room?

I'm a first time mom due in January and my birth plan is to have my mom and husband in the room with me but my sister INSISTS she has to be there in her words "I know you're having your first baby and all but I'm becoming an aunt" and I don't want to hurt her feelings but I don't really feel that it's her place =/ so how do you feel about having a sibling with you?
