Where does your cat sleep at night?

Just curious - for those with only one cat, do you let them roam free around the house at night? Or do you secure them in a room? Or do they sleep with you?

I adopted a 6 year old sweetheart a month ago. We secure him in a closed room at night (with enough space to run around if he wants to). I’m not sure if that helps him feel secure (we have kind of a large home).

I also think he would love the freedom to explore at night, but I worry he’d end up meowing at my kids’ doors (they like to sleep with their doors closed) or might startle me in the middle of the night haha.
