(Actually, even late in the propeller airliner era, Gander was obselete by 1957. The Douglas DC-7C Seven Seas and the Lockheed L-1649 Starliner achieved the ability to fly London to New York City westbound year-round.)
Most of the people in our company were in sales and liked the proximity and night life of midtown Manhattan, complete with very expensive hotel rooms slightly larger than deluxe broom closets.
I was there for actual work and needed a place for real work and rest, so got a spacious room for about half what they paid not far from a short train ride into Midtown. I remember it mainly because the company beancounter questioned me about how I'd paid so little for a hotel in NYC when I turned in my expense report.
