Traveling in Krakow
While Krakow has no underground metro, it does have a comprehensive bus and tram system. Check timetables and network maps online at http://www.mpk.krakow.pl/en/ or https://jakdojade.pl/krakow/trasa/ (choose the English language in settings - button in the top-right corner of the main page), and purchase tickets from the ticket machines at major stops, on-board of most trams and buses (in designated ticket machines). Note that the ticket machines at bus stops accept payments by cash and card, but most of those on board of trams and buses handle coins only - have some change ready.
In Poland type E power sockets are mostly used. The standard voltage is 230V (50 Hz). The power sockets also work with plugs C and with plugs F (equipped with an additional pinhole).
The official and operating currency in Poland is the Polish Zloty (PLN, zł.)
1,00 zł ~ 0,23€ ~ 0,21£ ~ 0,26$
Payment by credit/debit cards (e.g. VISA, Mastercard) is a widely accepted method in Krakow.
September is the time of beautiful Golden polish Autumn. Although typical weather is mild and sunny with an average daily temperature of around 17°C (63°F) (highs: 26°C [79°F]) , please be prepared for lower temperatures in the mornings and late evenings (even 8°C [46°F]). Please consider that in September in Poland rain is a quite common occurrence - it is recommended to have an umbrella and/or raincoat.
