yeah! or, at least, the spot where their room used to be now has a different room number on the door, if they'd notice that.

doors have locks and residents have their own keys to their own rooms. for security reasons, there's an anti-apparition charm around the building. people can't apparate inside of henhurst or into the rooms but they can apparate to just outside the entrance of the building.

there's no anti-disapparition jinx preventing people from leaving, so they can pop out whenever they want (as long as it doesn't coincide with apparating into a place with an anti-apparition charm) if that makes sense??
