I think there is potential for using smart contracts for traditional agent based hotel bookings. Settlement of these booking between the agent (ie., booking.com) and the hotelier is a messy and complicated process. It varies from invoicing or manual transfer, to generating virtual credit cards and emailing them to the front desk. Using a contract to do this actually makes a lot of sense and could limit breakage (where the supplier doesn't or can't charge the agent for the booking). My main concern about this (which isn't addressed anywhere in the white paper) is privacy. If this is done poorly, you are effectively linking accounts on a public ledger with real world locations and dates. Not only that, the guest and the host know a lot about the financial state of each.
