In the interest of our Summit attendees’ health and safety, ATI is committed to following the guidance and standards of Seattle health authorities related to COVID-19. As relevant COVID-19 standards continue to develop and evolve, ATI will provide information about what to expect onsite during our event. This information will be delivered to attendees on or before March 1, 2022.

Check back here often for the most up-to-date information and resources.


We will be following all local guidelines and authorities for King County and the State of Washington:

Yes, we will be requiring proof of full vaccination or a negative COVID-19 test taken within 72 hours to enter the Summit. This is required under a current King County local health order. We will share more details soon on how to provide proof of full vaccination as well as testing options.

Yes, Washington State currently has a statewide mask mandate for all individuals, regardless of vaccination status, for indoor events as well as outdoor events with 500 or more attendees. We will provide masks to all attendees at the event.

We are following the recommendations of the CDC and complying with applicable requirements of the State of Washington and King County regarding vaccination, testing and wearing a mask.  See above.  We will also require all attendees to agree to our COVID-19 terms, which include obligations of each attendee relative to COVID-19 health and safety protocols while attending the Summit.

The Hyatt Regency Seattle has a variety of measures in place to keep event attendees and hotel staff safe and comfortable.

  • Masks are required for all guests, regardless of vaccination status, for all attendees and hotel staff, in all areas of the hotel including guest facing areas, “back of house,” and offices. Masks may be removed when actively eating and drinking or in private guest rooms.
  • The Hyatt has hand sanitizers stationed in all public areas and outside each event space.
  • The Hyatt’s indoor air filtration system uses the highly rated Merv13 filters and charcoal filters. The meeting space is on a separate HVAC system from the guestrooms.
  • Daily Electrostatic Cleaning and hourly cleaning of high touch areas.
  • Social Distancing signage in public spaces
  • As part of Hyatt’s Global Care & Cleanliness Commitment, Hyatt Regency Seattle has implemented new standards and procedures. This multi-layered commitment includes an accreditation by the Global Biorisk Advisory Council, associate training and support resources.

If you test positive for COVID-19 within 72 hours of the event and are, therefore, unable to attend, you will receive a full refund. Proof of positive test will be required.
