The conference window IAAPA publishes
The IAAPA Public Affairs Conference 2027 runs in person from March 1 to March 3, 2027. The event page lists the time as All Day EST and the venue as Sofitel Washington DC, 806 15th Street NW, Washington, DC 20005.
The page describes the conference as direct access to lawmakers, with sessions with industry leaders. It prints no per-session clock and names no Capitol Hill address, so the daily shape of March 1 through March 3 has to come from IAAPA directly.
Registration is $499 for members and $999 for nonmembers. Early Bird pricing ends December 31, 2026.
The rate the conference block charges
IAAPA has secured a Sofitel Washington DC Lafayette Square rate of $349 per night plus taxes and fees for stays from March 1 to March 3, 2027. The page asks for bookings by February 9, 2027, with a cut-off at 4:59 p.m. EST that day, and states that rooms are limited.
The Know Before You Go block states that the registration fee does not include accommodation or airport transfers, and that attendees may arrange their own rooms.
What the same address sells by the hour
A Dayuse Washington listing read on October 24, 2026 carried a Sofitel Washington DC Lafayette Square card with a 9 a.m. to 6 p.m. window at $169, marked 25 percent below a $223.50 comparative rate, with no booking fee on the card. That is nine hours at 806 15th Street NW for less than half the $349 conference night, and the window covers a full conference day plus the walk back afterward.
The card prices the day of the read. The listing publishes no March 2027 inventory, so the search has to be re-run on the conference dates before anyone books.
The same page states that the average day room in Washington is $109.92.
Six more rooms inside a mile
Six other cards on the same read carry a District of Columbia breadcrumb. Distances below are straight-line from the 806 15th Street NW pin at 38.9005, -77.0339.

The March 2 evening sits on M Street
IAAPA gives conference attendees complimentary admission to IAAPA Meetup: National Geographic Museum of Exploration on the evening of March 2, 2027. The museum sits at 1600 M Street NW, Washington, DC 20036.
From the 806 15th Street NW pin, the Beacon card sits 0.13 straight-line miles from 1600 M Street, the Capital Hilton 0.17 miles, Le Meridien 0.21 miles, the Viceroy 0.30 miles, the Sofitel 0.41 miles and the AC Hotel 0.93 miles. The museum publishes no March 2 door time, so ask IAAPA for the access window.
Sizing the window
hotelslots.org sells four windows: Morning 6 a.m. to 12 p.m., Afternoon 12 p.m. to 6 p.m., Evening 6 p.m. to 12 a.m., and Overnight 12 a.m. to 6 a.m. Two adjacent windows cover a full day. The platform states that it is free to use, that it charges no booking fees, and that the guest pays the hotel directly for the slot. It publishes 103,857 hotels across 46 states and a 30 to 75 percent band below the nightly rate at the same property.
The District of Columbia carries no page in the hotelslots.org directory. The priced cards in this piece therefore come from the Dayuse Washington listing, and each card carries its own booking fee, listed per property above.
What to do first
Register before December 31, 2026 to take the Early Bird rate. Reserve a conference night by February 9, 2027 at 4:59 p.m. EST if the Sofitel block is part of the plan. Then re-run the day-room search on March 1 through March 3, and ask IAAPA for the session grid so a day window matches the hours the conference runs.
