This document discusses how hotels can generate revenue from unused rooms by bartering them for advertising through a company called Ormita. Bartering rooms for advertising allows hotels to maintain their advertising budgets without spending cash, reach new potential customers, and receive referrals. The process involves hotels providing empty rooms to Ormita in exchange for advertising placements. Ormita then finds businesses that can use the rooms and any profits beyond the room costs go to the hotel. This allows hotels to gain new customers and visibility without discounting rates or spending cash on advertising.
