Well, I've a strange question..
It seems that our 3 days in Vienna (next Thur-Sat) will fall in the midst of another heat wave. Thankfully, our hotel has aircon..
But the question is - are the museums and the palaces (the Schatzkammer, the Belvedere, Schonbrunn palace, Kunsthistorisches Museum, House of Music and so on) air-conditioned? Where should we go while it's hot and what places are inadvisable? We're a family with two boys (16 and 12) that comes to Europe in August to escape the heat in Israel :-)
