Radisson's latest TV campaign focuses on the business traveler-not unusual except for the occupations of those featured. One spot centers on "Anna," a ballerina and arranger. The other highlights the more typical occupation of salesman; however, this person sells violins made by his family's business. Sawtooth Group, Woodbridge, N.J., created the multimillion-dollar campaign for Radisson Hotels Worldwide. The commercials are running on network and spot TV in New York, Los Angeles and Chicago.
