One day, one daytime window
More than 1,200 housing leaders met at Moscone Center on Thursday, 24 September 2026 for the 47th Annual NPH Affordable Housing Conference. The organiser's conference page puts the doors at 8 a.m. and the close at 5:30 p.m. The venue's own event record places the day in Moscone South.
That window runs nine and a half hours. Hotels sell day-use rooms in morning, afternoon and full-day blocks, so a conference day of this length sits inside a full-day block.
What the venue's own feed shows
Moscone publishes its event record as a data feed at moscone.com/v1/events_endpoint. The feed carried 174 events on this read, dated 5 December 2021 to 31 July 2027. Eight of the 174 run a single day. One single-day record falls in 2026, and it is this conference.
The feed gives September 2026 three bookings. Salesforce Dreamforce 2026 runs 15 to 17 September. The NPH conference runs 24 September. CoreWeave Fully Connected 2026 runs 29 September to 1 October. The venue tags the conference Conv / Tradeshow and places it in Moscone South.
The daytime inventory in the district
Dayuse lists a $119.61 average for a day room in San Francisco on this read. Its recommended city property is The Mosser Hotel, which it places within a five-minute walk of Moscone Convention Center and a three-minute walk of Powell Street BART. Dayuse shows a $91 day rate against a $299 nightly rate at that property.
hotelSlots publishes its day-use band as 30 to 75 percent below nightly rates on its home page and 40 to 60 percent on its day-use page, with pool, gym, Wi-Fi and shower access included.
Where the daytime demand lands
hotelSlots lists the daytime price drivers as the time block, the day of the week, the location, the property class and the event calendar. Its guidance puts weekday day-use rates below weekends and says local events lift daytime slots with the rest of the market. A 1,200-delegate Thursday at Moscone South is a local event with an 8 a.m. start.
The rate the night sits on
Engine's San Francisco page puts the city's average nightly rate at $165 across 3.1 million public rate observations from May 2024 to April 2026. Those are par rates, the cheapest publicly available price at the time of each search. September runs $192, which is 16 percent above the city average. March is the peak at $197, and December is the low at $129.
The demand unit
A 1,200-delegate Thursday, 8 a.m. to 5:30 p.m., is the daytime unit the district's day-use inventory sells against. The venue's own feed carries one single-day booking in 2026, and it is this one.
