Effective Oct. 15, Expedia will function as a sort of technology middleman between Marriott and hotel bed banks, wholesalers, and other redistributors that want to access its inventory. The move does not affect travel agents, tour operators, and other suppliers that have established relationships with Marriott.

Marriott and other suppliers “have challenges sometimes ensuring that their rates and availability are put out into the market in a way that customers understand what they are getting,” Okerstrom noted.

When asked about the problem of “rogue rates” getting into the hands of aggregators, Okerstrom responded, “We’ve developed sophisticated technology to ensure that rates are used in the way they should be used.”
