American tourists have officially opened the new cruise season on the Danube. The first ship with 143 passengers docked this morning on the pontoon of "Danube Tours", where it was traditionally greeted with a concert by the Big Band Ruse under the direction of Dimcho Rubchev. The season is expected to be very strong this year, with forecasts of a 30 percent increase in tourist ships coming to Bulgaria by river. Danube Tours alone already has requests to meet 140 ships.
