A Prague newby here:
1. From U.S. and would like to know if there are any cultural/social expectations regarding etiquette and behavior I should be aware of. Don't want to be the ugly American...
2. Looking for the easiest way to get from the airport to Old Town Square area - not necessarily the cheapest, just the easiest considering I do not speak the language.
3. Best way to get to Cesky Krumlov and reco for a one night stay hotel.
