Plan around

New York Fashion Week: NYFW typically runs in February and September — the September 2026 schedule runs 10–15 September 2026. Fashion-industry activity and hotel demand rise sharply around these dates.
US Open: In 2026 the tournament runs 23 August – 13 September, with main-draw singles from 30 August. Expect higher demand across the city, not only in Queens.
