Some interesting quotes:
Meanwhile, Marriott suffered a reduction in brand value (down 8% to US$5.0 billion) and its brand strength dropped from AAA- to AA+. Marriott has faced several challenges in the North American market from hacking scandals to persistent problems with its loyalty schemes. At the same time, the combined value of Marriott’s brands within the Brand Finance Hotels 50 ranking decreased by 30%, giving way to Hilton’s brand portfolio to claim the title of the world’s most valuable.
And:
the three fastest-falling brands this year (Westin – down 46%, Residence Inn – down 46%, and Sheraton – down 44%), and altogether 7 out of the bottom 10 worst-performing brands, are part of the Marriott portfolio, dragging its combined value down.
I have no idea how credible this source is, but obviously these comments will resonate here.
