William Astor's construction of a hotel next to his aunt's house worsened his feud with her, but with Boldt's assistance, Waldorf's cousin, John Jacob Astor IV, persuaded his mother to move uptown. On November 1, 1897, John Jacob Astor IV opened the 17-story Astoria Hotel on an adjacent site, and leased it to Boldt. The hotels were initially built as two separate structures, but Boldt planned the Astoria so it could be connected to the Waldorf by an alley. Peacock Alley was constructed to connect them; it was named so by New Yorkers for the parade of well-dressed, well-to-do people who strutted between the two fashionable buildings. The hotel subsequently became known as the "Waldorf-Astoria", the largest hotel in the world at the time.
