This is in the spirit of the What is a Word/Phrase™ series started by JLee with a special brand of Phrase™ and Word™ puzzles.
If a font shares a specific commonality with another font, it's an Arnold Hotel Font™.
Use the following examples below to find the commonality. Clarification: This is asking specifically about the typeface being used, not the name of the typeface/letters contained within.
And, if you want to analyze, here is a CSV version:
Arnold Hotel Font™, Non-Arnold Hotel Font™

ANTONIO,VERDANA
UNIVERS,CAMBRIA
GOTHAM,BODONI
BEMBO,GILL SANS
AVENIR,LUCIDA
CHAMPION,PERPETUA

VITESSE,ONYX
CALIFORNIAN,PAPYRUS
Note: There are other Arnold Hotel Fonts™ than the ones on the list.
