In my case, I've never seen a Hawthorn Suites. They're not distributed as evenly as some of the other WyndhamRewards brands. For example, none in SoCal except way out in Victorville. And in general, they're only in about half the states (so there are whole groups of adjacent states with none in them).

Meanwhile, WyndhamRewards has tons of brands, and no one talks much about
most of them. They'll mention one brand or another in passing that they've stayed at, gotten a reservation at, etc. The brands with the most locations tend to get the most of those kinds of mentions, of course.
And did you search of this forum? People have talked about them in the past:
Are Hawthorn Suites falsefully advertising complimentary breakfast buffet ?
Hawthorn Suites by Wyndham Chicago Hoffman Estates
Review of Hawthorn Suites Kent (Seattle) WA
That's about on par for any brand-specific discussions I've seen in the WyndhamRewards forum: Once in a rare moon (and thus almost never on the front page of the forum).
