Nine dates, no room block
The Brooklyn Book Festival runs 20 to 28 September, nine days of free literary events in person and online. The festival sells no room block and charges no admission to its flagship day.
The published calendar sets the shape. Virtual Festival Day runs Sunday 20 September, noon to 5pm, online. Bookend events run from 20 to 28 September at venues across all five boroughs. Children's Day takes Brooklyn Borough Hall and its plaza on Saturday 26 September, 10am to 4pm. Festival Day and the Literary Marketplace take the same address on Sunday 27 September, 10am to 6pm, with eight indoor and outdoor stages and a marketplace of 250 publishers.
That calendar delivers two back-to-back daytime blocks and one hard peak on Sunday 27 September.
Manhattan runs the same dates
Climate Week NYC runs 20 to 27 September, hosted by Climate Group, with more than 100,000 people across 1,000-plus events. High-Level Week at the United Nations runs 18 to 28 September. Both concentrate in Manhattan.
Brooklyn takes the spill, and it takes it across the two days that carry the footfall. The citywide print shows what a full Manhattan does to the whole market.
The print going in
CoStar's release for the week ending 12 September 2026, published 17 September, has New York City posting the largest gains among the top 25 markets in all three metrics: occupancy up 4.1 percent to 91.8 percent, ADR up 7.1 percent to $435.43 and RevPAR up 11.5 percent to $399.60. The same release records the end of a 21-week run of national year-over-year growth, with the United States at 62.3 percent occupancy, $160.57 ADR and $100.08 RevPAR.
The prior print shows the swing. For the week ending 29 August, New York City registered the only double-digit ADR drop among the top 25, down 12.3 percent to $279.72. The gap between that print and the 12 September figure is $155.71.
The full-year base sits below both. The State Comptroller's July 2026 report puts 2025 citywide occupancy at 84.1 percent, ADR at $333.71 and RevPAR at $280.71, on 38.1 million room nights sold, 2 percent above 2024. The same report forecasts 2026 growth of 1.2 percent in demand, 4.4 percent in ADR and 4.8 percent in RevPAR.
The spread the week carries
CoStar's two prints put the citywide ADR gap at $155.71 inside three weeks. Set your Friday and Saturday number against your Sunday-to-Thursday number for the festival dates, and hold that difference through the pick-up window.
The festival's single-day peak lands on a Sunday, at the end of nine days of free programming that gives the submarket no booking window in advance. Hold the Sunday inventory back from the discount, and let the pick-up set the last rate.
The cost floor underneath
Brooklyn's wage bill sets the level this demand has to clear. Average annual pay in borough hotels reached $60,259 in 2025, 31 percent above 2019. The Hotel and Gaming Trades Council's eight-year agreement with the Hotel Association of New York City, reached in May 2026, covers 250 hotels and 27,000 workers and carries wage increases of 50 percent over the term. Brooklyn's hotel establishment count reached 147 in 2025, from 115 in 2019.
Supply stays constrained where the demand is. The Comptroller's July 2026 report puts the city pipeline at 24 projects with 5,778 rooms in active development through 2028, against 15,777 rooms under construction in 2020.
What the week asks for
Hold the Sunday. The peak is one day.
Price the two daytime blocks as one run. Saturday 10am to 4pm and Sunday 10am to 6pm carry the footfall, and the Bookend evenings fill the nights around them. Operators selling daytime and hourly inventory have a Saturday and a Sunday window inside a week of full Manhattan hotels.
Watch the short-lead curve. Free programming gives no booking window in advance, so the rate decision has to be made before the pick-up arrives.
