"The coronavirus or COVID-19 is has become the worst event ever to have impacted Marriott's (
MAR) business"
I dunno about that. The loss of a Marriott family member at the helm and appointment of Mr. Sorenson seems to be the worst event in Marriott history I can think of.
As a side note, the article says Marriott spends $1BN on marketing a year. Where? Unless they're talking about all of the dumb things with BoNVOY written on it plastered around the hotels, I've never seen anything about Marriott or Bonfire in the wild. Surely the bloggers aren't eating up $1BN worth of referrals and free stays?
