Cocktails and a buffet supper will then be servedin the various rooms around the building, with a chanceto stroll around to meet old friends, while viewing thestunning architecture and decoration of the variousrooms. Mavel will co-host the evening, withHydropower & Dams.Tuesday 18 OctoberImmediately after the afternoon sessions of theconference, an apéritif will be served in the HYDRO2011 Exhibition Halls, providing extra networkingopportunities in a relaxed atmosphere at the end ofthe working day. Delegates can then enjoy an eveningat leisure, either exploring the city, or attendingvarious privately organized parties hosted by majorcompanies in the hydro industry.Wednesday 19 OctoberThe Farewell Dinner will take the form of a countryparty with a medieval-style banquet, at the VillaDreucici, a former fortress dating from 1050. The villais in a rural setting, a short coach ride from the centreof Prague.Music and entertainment is planned for the evening,as well as a feast of local specialities.The Czech utility CEZ will co-host the evening with theHydropower & Dams team.
