Well, maids are paid to clean the room, not just 'tidy' it up. But you can certainly make it easier on them.
I clean up the room a bit just to make sure I haven't left anything behind. So all trash is in the garbage, all towels are in the bathtub, and all the bedding is shook out and piled on the bed, and I've made sure my cell phone charger or book isn't hiding somewhere.
The way I explain it to my students is the custodians are paid to maintain the school not clean up their messes. I feel the same way about the maids in hotels. I leave the room neat so they can do their job.
It's the same reasoning as 'cleaning for the cleaner'. When I had a housecleaner coming in every week, I would make sure that stuff was picked up and put away. She was there for 4 hours and I wanted her to vacuum the house, dust the LR, mop the kitchen floor and clean all kitchen surfaces, clean the bathroom top to bottom, plus do an extra job like wiping out the fridge, waxing the cabinet doors, or cleaning the oven on a rotating basis.
So it made sense to me to tidy up as best I could, so that she could get right to the real cleaning. If I left dirty dishes in the sink, and junk and clothes all over the place, she'd be taking time to do the 'easy' stuff (plus she wouldn't even know where to put things), and not doing the jobs I was paying her to do.
Hotel maids have to:
-Clean the bathroom top-to-bottom
-Vacuum the room
-Change the bedding
-Remove all trash
-Wipe all surfaces
-Replenish all supplies (coffee, cups, soap, towels, etc.)
If you haven't cleaned your spilt coffee or makeup off the counter, or haven't tossed your food garbage and FF wrappers, they have
to clean that up too, but they shouldn't
have to, as no self-respecting adult should be leaving that kind of mess for someone else to clean up, IMO.
