I'm "meh" about the Hampton Inn breakfasts as well. Coffee, cereal, waffle, banana - they're all ok. The breakfast "meat" of the day is sketchy. I don't eat eggs so I can't comment on those. The breakfast is typical of a chain that gives free breakfast to the masses. Holiday Inn Express is slightly more enjoyable because of the cinnamon rolls but they serve generic brand cereal.
HGIs are always my first choice because of the excellent breakfast buffet (free for Gold/Diamond).
