Ther are some good maps on the internet also.
Electrical adaptors the plug sockets in Prague are slightly diferent than europe the have a fixed earth pin which slots into the plug, we have several adaptors but the one we took did not have a hole in the adaptor to take the earth pin when I looked at the adaptors when we arived back home some of then have this hole.
We had to buy an adaptor in Prague at a big store on Revolution near the powder tower when we were looking in the elecrical department the lady knew what we were after and it cost 160Kc about £4
A razor plug if ok as it just as the two pins
