I agree with that, as its important to remember that (at least in our case) guests are coming for holiday, and often duly "switch off". They don't want to be happy ded a list of petty things that they must do. Although most are conscientious about basic cleanup, they're unlikely to empty the coffee filter or empty the rubbish bins. Many do, but it's rather petty list every little item. You should assume they won't.
However there's a few things worth pointing out. For example, our dishwasher has a variety of programmes. The 45 minute programme works brilliantly. The other programmes can consume thousands of watts of energy for hours, with little if any discernible difference. So it's worth pointing that out.
Guests are there to relax and get away from it all. Having too many rules, particularly petty ones, can seem a bit overbearing, especially when thats what they're trying to avoid. And if it's something they'd always do anyway, it can be a bit insulting, as if you're expecting them to behave that way. What kind of place are you running here? Do most of your guests live that way?
Just my tuppence.
