The interior design of the hotel also underwent several changes. Artist and interior designer Henry Lovins originally suggested a "Mayan revival" theme with Hispano-Moresque influences. However, the husband and wife team of Professor Arthur Upham Pope and Dr. Phyllis Ackerman was selected over Lovins. Drawing on their experience as art historians, Ackerman and Pope created a style that mixed Art Deco, Native American, Middle Eastern, and Arts and Crafts styles. The interior work was carried out by a number of artisans under their supervision. Much of the decoration originally used was Persian, and Ackerman and Pope would go on to become consultants in Iran.
