Just wanted to throw my hat in for another Hilton sub-brand: Hilton Suites, which is where I'm writing this in Brentwood, TN. Looks like this was another brand at one time and not a Hilton original. Suites are smaller than what you'd get at an HS, though not as nice as an ES, though the atrium layout does ring a few bells.
Suspect if they didn't already have the suite configuration in place this would be an HGI (although no free Internet access here) as the restaurant is a Great American Grill.
Decent property for $129. Sidebar: Sticker shock when you get the final bill in these parts: 17.5 percent taxes! That's something to write a country song about.
