I had 6 days in Prague last July , brilliant place - if you are there on a Thursday , there is a tour that runs from Prague to the Skoda Factory and Museum at Mlada Boleslav , well worth a day out! If you can , check out Kutna Hora , Cesky Krumlov and Karlovy Vary as well , tours to all these places are sold from Kiosks on one of the main streets , Na Prikope , just off Wencleslas Sq. PS Dont drink in the British or Irish pubs , they are twice the price of the smaller local places.
