Alice's Hotel has noticed that they spend a lot of money on water and electricity devoted to washing linens (towels, sheets, and pillowcases). In order to reduce this expense, the owner wants to encourage guests to reuse linens for more than one day. What would be the best way to accomplish this task?

Put a note on the bed indicating that most of their guests reuse linens, and asking this guest to do the same.

Explanation:

The most effective way of passing information to guests in a hotel is by using notes in the most obvious of areas such as the bed or table.

This makes it easy for every incoming guest to receive the information.
