Tourist cities should have hotel rooms by the hour that are actually clean when you just want to take a nap.
There’s this suit of useful little programs called Microsoft PowerToys, I always thought it should include a tool that allows you to quickly swap the contents of monitors around in multi-monitor setups.
e.g. move all open windows from monitor 1 to monitor 2 and vice-versa, while retaining their (approximate) position.
This may already be a thing, I haven’t really checked.
I use KDE Plasma on a regular basis but I’m not aware of that being a feature. Maybe you can do it with virtual desktops, though.
I have a keyboard combination shortcut for switching windows from screen to screen in kde plasma
