Have you ever run the cost of breakfast per room/person, or has that not been a need? When I did a rough calculation, the cost of food + labor help on busy mornings works out to more than $10/person.Lots of places are doing that in order to have their rooms look cheaper on OTA sites. I have no idea how you would track that in the morning during the breakfast scrum. Do you forbid them tea and coffee as well?
We have a lot of self serve items out all the time. I doubt we'd save money not including breakfast in the room price..
