Riverside Convention Center — Riverside, CA


The 2023 Annual Meeting will be held at the brand-new and extremely spacious Riverside Convention Center.  

We have pre-purchased a limited block of hotel rooms at three of the hotels adjacent to the convention center.  These hotels are each within one block of the convention center in easy walking distance.  

  • Marriott Downtown Riverside (Room block expired on January 20.) Block 1:  $150/night AND Block 2:  $165/night.  Due to a recently increased federal per diem rate, we have rooms available at two different rates. Both rates are available to anyone in our group, and you do not need to be a federal or state employee to book in either block.  First come, first served for the lower cost rooms.   Price includes 20% breakfast discount in C3 Restaurant, and free high speed internet.  Valid February 6-10, 2023.  Rate expires 1/20/23.
