You know, it's not that unique if there's a "Your location Here" space.

A small chain. This story on the hotel's future describes its opening:

The year was 1919, and the hotel was the elegant Fort Des Moines. It had 400 rooms and 400 baths and a Grand Ballroom that would hold 400 people. It had “Permutit softened water” and all the amenities a demanding traveler would demand at rates of “$2.00 per day and upward.”

If you're wondering: "Permutit is the trade name of a synthetic zeolite of the approximate composition 2 SiOz, A1203, NanO. 6Hz0, first manufactured by a German chemist, Robert Gans,' which has been used industrially for softening hard water and refining sugar."

Wonder no more.
