Due to limited parking lot capacity, a shuttle service with buses is offered to bring people to Warnemünde. Sponsors have included "Hanseatische Brauerei Rostock" (German brewery), "Ostdeutscher Sparkassenverbund", and "OstseeSparkasse Rostock". Further sources of revenue are letting of boat parking spaces and trading places on markets as well as commercial advertising. The City of Rostock supports the Hanse Sail financially, because the city largely profits from the event. During the sail, most hotels are usually fully booked and visitors spend money in the town, in pubs and shops. Last, but not least, the sail is good promotion for Rostock and a good percentage of Hanse Sail visitors usually return for a holiday.
