Even though the Czech Republic is part of the European Union, the Czech crown is the official currency and enjoys strength and stability. Some stores, restaurants and hotels will accept euros, although the exchange rate may not be favorable. Youth and family hostels abound, as do rental apartments, guesthouses and inns. During the summer, universities open student dorms to visitors for economical lodging. Take in the free open-air theater at Divoka Sarka in late summer. For the most part, however, April and October have smaller crowds and cheaper rooms. Anytime you visit, avoid eating near tourist sites. Venture a bit further for less expensive canteens and cafes.
