In order to keep the cost of the conference as low as possible, we committed to a minimum number of room reservations. If we are unable to meet this minimum, we will incur a significant financial penalty. You can help AoIR avoid this cost by reserving your room at the Sonesta Hotel Rittenhouse Square. This will help AoIR maintain its financial health and keep our registration costs for future conferences at reasonable levels for everyone. All reservations must be individually made by conference attendees.
