24-hour restaurant next door. Cocktail lounge! Switchboard! Factor in the pool cleaner and housekeepers, and there were quite a few people who owed their livelihood to the Sundial. And perhaps they still do. From a bio of a California lodging association board member:

Fate brought him into the hospitality industry in 1974, when he first started to operate and manage the Millwood Inn, Millbrae. He then acquired the Best Western Sundial Motel in Mountain View, in 1976 and after four major renovations they became Holiday Inn Express product.

Unrecognizable now, and the address is different. History is elusive.
