Hotel Information

Any changes or cancellations needed for existing reservations at the San Francisco Marriott Marquis Hotel will need to be made directly with the hotel by calling Marriott Reservations at 888-575-8934.

Given the surge in early registrations for SIIA’s National Conference & Expo, the block of discounted sleeping rooms at the San Francisco Marriott Marquis Hotel is now sold out. It may still be possible to reserve sleeping rooms at the “market rate,” but we anticipate that the hotel will be fully sold out well in advance of the conference so you should contact them directly right away at 415-896-1600 should wish to stay there.

Alternatively, we have included a list of nearby hotels below. We are aware of other large business conferences scheduled in San Francisco during the same week as SIIA, these other hotel are expect to be sold out in the coming weeks and months, so you are highly encouraged to make a reservation now, even if you are not sure whether you will be attending the SIIA conference.

You may also want to consider non-hotel lodging options that can be booked through such companies as Airbnb or Homeaway as their is significant inventory in downtown San Francisco.

The Marriott Marquis does have suites available. If you are looking for personal suites and/or private meeting room please use the links below.
