In FY11, $20.6 million in sales tax revenue ($1.07 million) and hotel room tax revenue ($19.5 million) were left behind by conventioneers visiting San Diego as a result of spending for accommodations, dining, shopping and other goods and services they used while in town. This is a 1.8 percent increase above FY10. That's good news for San Diegans because these revenues help to pay for police and fire protection, street and park maintenance, upkeep of museums and beaches, and other city services residents enjoy and that contribute to our quality of life.
