Photonics West 2027 and its three floor days
SPIE Photonics West 2027 runs 30 January to 4 February at the Moscone Center in San Francisco. The venue event page prints the window as January 30 to February 4, 2027, and SPIE places the week across Moscone North, Moscone South and Moscone West.
The week carries two exhibitions. The BiOS Expo runs 30 and 31 January. The Photonics West Exhibition runs 2, 3 and 4 February. Monday 1 February carries conference and course programming and no show floor.
SPIE counts 24,000 people across the week, more than 4,500 presentations in six technical application areas and more than 1,400 exhibitors across the two exhibitions. The six areas are AR | VR | MR, BiOS, the Embedded Vision Summit, LASE, OPTO and Quantum West. The Embedded Vision Summit joins Photonics West for the first time in 2027. The exhibition carries Quantum West, Vision Tech and AR | VR | MR. Five industry stages and the three-day Quantum West Business Summit sit inside the same week.
The hours between a session and a floor pass
A delegate meets the gap between a conference morning and an afternoon meeting. The bag and the laptop come along.
A day room covers that gap. hotelSlots books day-use rooms in four published windows: morning from 6 a.m. to noon, afternoon from noon to 6 p.m., evening from 6 p.m. to midnight and overnight from midnight to 6 a.m. The platform states that a guest can book one slot or combine several for full-day coverage, and its glossary defines a day-use room as 6 to 8 hours.
The platform publishes day-use rates 30 to 75 percent below the nightly rate at the same hotel. Its network covers 103,857 hotels across 46 states, and a submitted request carries no booking fee.
The remote-work page describes the product as "A quiet, professional space with reliable Wi-Fi", with "Desk and ergonomic seating", business-grade internet and "Privacy for calls". The day-use page adds "Pool, gym, Wi-Fi, and shower access included."
What a San Francisco day room costs
Day-use pricing in the city, read on 15 October 2026 from dayuse.com's San Francisco city page: nine cards carry city districts and run from $91 to $159, and the average of those nine figures is $128.00. The page's own published line reads an average price of $119.61 for a day room in San Francisco. Both figures carry the read date and they move between reads.
The Mosser Hotel at 54 4th Street carries the lowest of the nine at $91, a 70 percent discount against a $299 comparative rate. The card lists five windows: 8 a.m. to 2 p.m., 10 a.m. to 4 p.m., 11 a.m. to 6 p.m., noon to 7 p.m. and 2 p.m. to 10 p.m. The same card places the hotel within a 5-minute walk of the convention centre, the Powell Street BART station within a 3-minute walk, and parking at an extra fee.
The rest of the city set: Hotel Caza Fisherman's Wharf $107, Hilton San Francisco Financial District $116, Axiom Hotel $122, Buena Vista Motor Inn $123, Hotel Zeppelin $138, Hotel Zelos $144, Hotel Zetta $152 and Taj Campton Place $159.
Which window covers which day
The floor runs 2, 3 and 4 February, and all three days are weekdays. A 10 a.m. to 4 p.m. window sits inside the middle of a show day. An 8 a.m. to 2 p.m. window covers the hours before the doors and the first part of the morning on the floor. Two windows stack into a full working day.
Monday 1 February is the day a day room covers the most. The BiOS Expo closes on 31 January, the Photonics West Exhibition opens on 2 February, and the Monday carries programming with no exhibition attached.
Reaching the doors
The venue directions page sends BART and MUNI riders to Montgomery station for Moscone North and South and to Powell station for Moscone West, and it states that the Moscone Center does not have on-site parking. The Moscone Center is at 747 Howard Street and Moscone West at 800 Howard Street. Both carry the 94103 ZIP code.
Book the day-room window before the week.
