Stop Online Booking Scams Act of 2017 This bill prohibits third-party online hotel reservation sellers from charging a consumer's credit card or financial accounts in an Internet transaction for a hotel unless they disclose: (1) a description of the offered good or service, the cost, and other material terms before the conclusion of the transaction; (2) that the third-party seller is not affiliated with the hotel owner or an entity that provides the hotel services or accommodations; (3) that the third-party seller is not an exhibition organizer, a meeting planner, or the official housing bureau for an event at the hotel; and (4) the brand identity of the third party online or over the phone. The bill provides authority to the Federal Trade Commission (FTC) and states to enforce against violations. The bill also expresses the sense of Congress that the FTC should revise its website to make it easier for consumers and businesses to report complaints of deceptive practices with respect to online booking of hotel reservations.
