Identify yourself as attending the PIUG 2026 Joint Annual and Biotechnology Conference.

Message to Attendees: PIUG has made every effort to secure the best possible group nightly room rate for you at this event. That rate results from a negotiated overall package of event needs such as sleeping rooms and other requirements. Contracts with the venue include a provision to reduce event costs if PIUG meets or exceeds its minimum sleeping room block guarantee. Conversely, event costs will increase if PIUG falls short of its minimum room block guarantee. Please help PIUG keep the costs of this event as low as possible by booking your housing needs at the designated host hotel and through the reservation process created by PIUG. Reserving elsewhere means you are booking outside the contracted room block, jeopardizing PIUG's ability to meet its contracted obligations and to keep registration fees to a minimum. PIUG appreciates your support and understanding of this important issue. Thank you.

Additional benefits: 

• Complimentary wireless internet.
• 25% off valet parking.

Check-in time is 4:00 pm. Check-out time is 11 am.

Please remember to make your hotel reservation prior to 5:00 PM EDT on April 27, 2026 in order to guarantee the room prices negotiated by PIUG for this conference. After that, it is at the hotel's discretion to accept additional reservations, which will be subject to prevailing rates and availability. Depending on availability, the hotel will honor the PIUG room rate from May 16 - May 24, 2026.  Please contact admin@piug.org, if you need assistance with booking a room.
