We are a tourism promotions company and are planning a promotion in a large city in the northeast this year. We plan to give away 50 vacations to the winners of a drawing. The entry forms and entry box will be located in restaurants, grocery stores, convenience stores and other public places. We are considering a small amount of radio advertising for this promotion, assuming we can find a radio station who will also be a sponsor to contribute additional air time in exchange for the sponsorship.
Any ideas on whether we are making a good or bad choice for the advertising medium?
