Hello, I will be arriving Prague in April, at night around 20:00. I am thinking of directly going to Liberec from the airport since I have to attend a meeting there. What is the best route to take to arrive Liberec? (best as in cheapest + safest) Arriving at 20:00, do I still have time to use public transportation? Is there a shopping center in Liberec? Like many shops with good prices to buy? Its my first time to Czech.
