Maybe I'm just plane naive here, but going on vacation and especially Disney is a treat. I can't believe kids can't deal with situations where they have to sleep with their siblings. I have a sister and we are three years apart. When we traveled, we slept in the same bed, if we didn't like it, there was always the floor. My parents would never split us up. Same with my cousins, boy and girl, they either learned to deal with each other, or hit the floor! These are siblings, have I missed something, they live in the same house, use the same bathroom, etc etc, can't they just get along and sleep with each other for a vacation?
