In the aftermath of the passage of Arizona's immigration law, SB1070, the Arizona Hotel & Lodging Association reports that 19 groups have canceled events in the state, representing 15,000 room nights. The new law requires state and local police to determine the immigration status of people if there is "reasonable suspicion" that they are illegal and to arrest people who are unable to provide documentation proving they are in the country legally. Despite the growing boycott, several travel industry groups have voiced support for tourism in the state. Among them was Roger Dow, president and CEO of the U.S. Travel Association, who called for an end of all Arizona travel boycotts and urged Washington policymakers to address the complex issue of immigration.
