I run into the "early breakfast dilemma" when I do government travel to military bases as a civilian contractor. Starting at 6 am isn't that uncommon, so I usually end up eating breakfast out of whatever I can find at the 7-11. It's not bad, but breakfast at the hotel would be nice.

Recently, though, I've found hotels near base that start serving breakfast at 5 am, which is just early enough to scarf something down before driving onto base. And recently, one of the hotels I was staying at started their breakfast buffet at 4 am! They even told me the breakfast buffet hours in military time when I checked in.

But, yeah. In places where people would logically be up and out early, having that early morning breakfast available is nice.
