The hotel I used to work at provided amenities for guest rooms in refillable pump bottles. The custom-blended citrus castile soap (the most-consumed amenity) cost $2500 for 50 gallons. Some of the cost was recovered by selling soap in the hotel gift shop at $20 for 12 ounces, but most of the expense was borne by room rates. We used 50 gallons about every six months for 46 rooms and restaurant bathrooms.
Speaking of restaurants, I know the restaurant at my former employer certainly made money. The Embassy Suites in downtown Portland (some AU'ers stay here...) seems to have struggled to have a full-service restaurant;the three times I have stayed there, the restaurant was closed. I got room service once, and the food was very mediocre (possibly cafeteria food for employees?).
