I sure get it about the 5 loads of laundry between guests, and we are in a serious drought here. We scrub like crazy and replaced things regularly, because our standards are very high. Utilities are a real expense, as are repairs and replacements. Every little thing has to work, and be safe. We started in the hospitality business in 1972, and are still learning. If we ever think we've "got it", we'll soon get a surprise of some sort.
We provide about $12 in fresh food for guests, in the fridge, plus coffees, teas, hot chocolate, local chocolate candy. And things like locally handmade soaps. We are also 12 miles from town in the mountains, so we provide a lot of food for guests. Most don't use much, some nothing. If someone occasionally uses more than expected, it all balances out, imho.
