@elaineswann: The calculation is for each night of your stay. For example, 3 nights x $5 = a $15 tip for maid service at the end of your stay. Now, keep in mind that the schedules change, and you might not have the same person for each night. So, in this instance, you can leave a daily tip of $5 whenever you leave your room. This way, the person cleaning it can get the tip.
