The report, titled U.S. Groups & Meetings: The Economics and Complexity of Intermediation, estimates that groups and meetings cost the U.S. hotel industry $3.4 billion to $4 billion in 2017. Commissions paid to intermediaries accounted for $1.3 billion of that, based on a 10 percent commission rate. By 2022, the cost could reach $8 billion or $10 billion, according to projections from Kalibri Labs, PwC and Oliver Wyman. Kalibri serendipitously released some early findings from its research in January, just before Marriott International announced its intention to cut groups and meetings commissions in the U.S and Canada from 10 percent to 7 percent by March 31. But even with the largest hotel company in the world pledging to lower the money it pays out to intermediaries, Kalibri co-founder and CEO Cindy Estis Green said that, at the rate intermediation is growing, Marriott's move isn't enough to alter future projections.
