When they were REALLY little, like babies, they slept in their cribs. We'd bring them in if they were sick or scared.
As they grew, they'd only come in if they were really scared from a nightmare or thunderstorm. Actually, all three of them (even the 14 year old) will still come in if they're scared from something, and sleep with us till they feel better. But it is EXTREMELY rare.
But, when we travel, well, we just make it work however it needs to. Sometimes, the oldest will get the cot, the youngest sleeps with me and my son sleeps with my husband. Or the two girls sleep together, hubby and I together, and my son gets the cot.
We love "morning" bed on weekends. Usually, one by one they come into the room on Saturday morning, and we all cuddle and talk about our week and the weekend and stuff. Even the dog. Lots of fun.

In fact, hubby was out of town this week, and the 4 of us did it one morning. Took about an hour and a half of cuddling and giggling and playing games and stuff. LOL
