The internet never ceases to amaze me.
A hour ago I only knew the building as the Palomar Ballroom.
As one clue led to another...all the pieces fell into place.
It was originally built as the El Patio Ballroom, then it was Rainbow Gardens
and finally the Palomar Ballroom.
By knowing the ballroom's original name I was able to find this aerial.

The Bimini Baths and the Rayfield Building are on the left, and the El Patio Ballroom
(the future Palomar Ballroom) is on the right.
