...we always load/start the dishwasher.
I also wipe the kitchen counters and stove/frig quickly....leaving everything neat.
These two comments stand out to me. I often wonder if going to these extremes doesn't do more harm than good.
Regarding the dishwasher, it's my understanding that housekeeping is supposed to wash all of the everyday dishes, silverware and glassware between guests. (It actually does all fit in the dishwasher at once.)
So if guests run the dishwasher half-full, does that throw off the schedule of the housekeeper? (Still waiting for cycle to complete before they can move on.) Or more likely, they probably skip doing a second load. And when housekeeping doesn't wash everything, we start seeing comments to the effect of "I pulled a glass out of the cabinet and it had lipstick on it from the last guest!"
As for wiping things down, similarly my fear is that housekeeping will see things looking "good enough" and not bother to go through their normal routine using cleanser / sanitizer to properly clean those surfaces between guests.
Personally, I tend to leave everything in lived-in condition so that housekeeping knows which areas of the room have been touched and can properly prepare for the next guest. Our last dishes are usually left in the sink and I don't fret about a few crumbs left behind on the counter.
I'm not talking about purposely leaving spills or horrible messes unattended...I just don't want to give the housekeeper an excuse to skimp on proper cleaning procedures.
