Housing & Travel

The housing portal will open for booking in late August and will close 15 November 2023. AGU has partnered with over 50 hotels to offer discounts within our block.

IMPORTANT: If you are contacted by any company other than Maritz Global Events offering housing, please note that these companies are not authorized to represent AGU nor do they have access to officially contracted AGU23 room blocks or rates.
These unauthorized companies often don’t deliver on promises to customers. When customers arrive, reservations are non-existent, or the hotels are not conveniently located. Sometimes the rooms have been cancelled and hefty cancellation fees have been placed on the customer’s credit card. In addition, these companies’ practices make it more difficult for AGU to meet our room block commitments and expose AGU to penalties. If you have questions, contact AGU Housing Team.

AGU will not charge your credit card. AGU/Maritz Global Events will transfer your credit card information to the hotel approximately three weeks prior to AGU23. The credit card provided at the time of booking will only be charged by the hotel if you cancel within 72 hours of arrival or do not arrive on your scheduled date.

Yes. A detailed confirmation is automatically emailed to you once your reservation has been made and all requested reservation nights are available. However, if one or more nights of your reservation cannot be confirmed at the time of booking, you will not immediately receive a confirmation. Maritz Global Events will work with the hotel on your behalf to secure the nights needed to confirm your entire reservation, you will automatically receive a confirmation at that time.

There is a 72-hour cancellation notice required to avoid a penalty. If your reservation is cancelled less than 72 hours prior to your arrival, you will incur a one-night room and tax penalty from your hotel.

Oakland International Airport (OAK) is 20 miles from downtown San Francisco and the Moscone Center. OAK offers nonstop flights nationally and internationally.
