The Sheraton brand is very inconsistent, and actually is a luxury brand in some countries (outside of North America). In some countries Sheraton is positioned as a step up from Westin, for example. At least 5 of the 10 best Starwood hotels in the world are/were branded as Sheraton, fwiw (and not as Luxury Collection, for example, though lately some of the Sheratons have been changing names). It is a very confusing brand positioning, you never know what you get when you go to a strange Sheraton.
