90 years

On June 12th, 1929 it was possible to wake up in a $2 per night room in the tallest building in the British Empire. The night before was the social event of the year with the opening gala of the Canadian Pacific Railway's most grand hotel. It had 28 floors, 10 elevators, and 1,048 rooms. There was also a 12 bed hospital, a radio station, and a bank inside. Today, rooms start at $379 per night.
