Do they make a bed bigger than a king?

With last night's storm, I gained two extra people in my king-sized bed. At midnight, I finished a 3+ hour phone call with my mom and went up to check on the kids. Shane has been sleeping with Sarah a lot these days. She uses it as a bartering system when she has friends over. "Shane, if you let me and Kate play alone, then you can sleep with me tonight..." Pretty smart girl. I think she is comforted by him as much as he is by her. If she won't let him sleep in her bed, he sleeps outside her door in a little Star Wars tent. Hopefully they'll still get along like this as teenagers. I said hopefully. {picture to follow}

Anyways...when I went up to check on them, Sarah was wide awake, scared of the thunder. Steve was out of town, so I invited them down. I don't think any of us slept well. Shane was in the middle, but his knees and feet were on me the whole time. Next time, I think he is going sleep in the floor. I keep a pillow and blanket on my side of the bed so that when he shows up he has a place. Note, he came down often when he was allowed in the bed, but since I put out this blanket, he doesn't come near as often.

I read Cari's post about the 4 of them in the same situation, and I think they have a queen! Maybe I should just utilize the lock in the bedroom door?
