I worked at a luxury hotel chain while in college. I actually only worked there for 8 weeks because I just couldn't clean the rooms quick enough. I quit because I was pressured to do shortcuts I wasn't comfortable with.
Blankets and bedspreads were cleaned on a three month rotation. Sheets were only changed on odd number stays. For example, 5 night stay. The sheets would be changed on day three only.
Of course this was what the schedule allowed. There are many housekeepers that did not follow this rule. I was told to look things over to see if vacuuming an area would be enough. Yes, vacuum the sheets rather than change them. Even the shower, if it was passable.
This hotel was a suite hotel, so every room had a kitchenette. There was place settings on a counter area. I would take all the dishes from the sink and place settings and run them in the dishwasher as soon as I entered a room. I was actually written up for this. My supervisor actually showed me how just a little "heavy breathing" on the utensils would shine up the silverware. Glasses were only run under the tap, etc. The same goes for bathroom tumblers.
Whenever we go to the hotel, the first thing I do is take off the bedspreads. I also collect any glassware, etc and put it out of reach for the kids. I just bring solo and dixie cups to use. I also bring a baggie with premoistened cleaning cloths for the remote, phone, etc.
I call housekeeping if one of the kids was especially messy while in bed and ask them for a sheet change. And I never forget to leave my mousekeeping tip envelopes.
