I got one of these "spend a night on us" certificates from HGV after completing their tour. The certificate says it's valid for a "Hilton Hotels & Resorts" branded Hilton hotel. I tried googling this, but couldn't really find which hilton hotels are under that brand. Does anyone here know?

It also excludes specific hotels, namely, "Waldorf Astoria, Conrad Hotels & Resorts, Canopy by HIlton, Curio, Doubltree, Embassy suites, HIlton garden inn, hampton hotels, tru by hilton, homewood suites, home2suites, HGV."
