I work in a travel agency called Quality tours. For years we are hosts to many tourists, mostly retired people from Scandinavia, USA, Italy, who travel down the Danube from Vienna to Sofia (Orahjovo). As a part of our programme and also to give them impressions about the life in Belgrade. You would be a guest on the boat while it is stationed in Belgrade and just talk with them. That would mean a lot to them. The cruise starts from 20th of April till 22nd October.
