While I agree, the whole architectural treatment is already a stylized interpretation of a mix of existing source materials.
For example, the exterior references the Hotel Del Coronado in San Diego:

But it's lobby bears absolutely zero resemblance to the "true" Victorian lobby of the "Hotel Del" as we So Cal locals call it:

So obviously, the lighter and brighter lobby theming is taken from other Victorian era hotels, like the Grand Hotel on Mackinac Island in Michigan. Also, 6 story atriums were highly unique (with the exception of the Brown Palace in Denver, low ceilings were the norm and more practical within conventional architecture and engineering), so there's always going to be some "interpretation". Even the Brown Palace, with its 8 story wrought iron atrium and HUGE stained glass ceiling feels much darker than VGF.
