"It would useful to make people aware when they are booking that they cannot use toilet paper in the toilets on the boat. Would also be good to have a small bin with plastic bags and a lid for the used toilet paper. As an option you could also provide an option for basic cleaning equipment to be included such as dishwashing liquid, hand wash, spray cleaning, paper towels. You would need to charge people for this obviously however it would be one less thing that the client would need to bring. You could also do this for basic condiments such as salt,pepper, sugar, tea, coffee and charge people for this as an option ."
