I also would say no. For me, it feels weird that my kids aren't with us in the same house when we are sleeping. I wouldnt't be able to close my eyes. I also don't feel the need and especially when I don't really know the parents or haven't been at their house. I'm not sure at what age I would let them sleep at their friends's house. It's funny because as a child(I didn't have a good childhood) I was sleeping at different houses.
