–As shown by the link above, the motel still exists in it’s original configuration and location. The object in the water near the shore is a floating platform, to allow swimmers to rest further from shore and dive into the deeper water from the platform. It is certainly long gone by now, possibly replaced by something more permanent and safer.
The card is dated 1957.
