For AI x Energy attendees, we recommend staying in downtown San Diego, Mission Valley, or near campus. Close-in options by SDSU include budget and mid-range hotels along El Cajon Boulevard and Alvarado Road, just a 5–10 minute drive or a short trolley ride from campus. Mission Valley (northwest of SDSU) offers a wider range of full-service hotels—such as major Marriott, Hilton, and SpringHill Suites properties—clustered along I-8, with easy access to the SDSU Trolley Station and quick connections to downtown, the airport, and the beaches. Downtown San Diego also has many hotel options with convenient access to SDSU via the MTS Green Line Trolley.
