I am soooo confused! What is the best way to get from the airport to Prague Old Town area? I have been searching and it's making me nuuts! I found airport shuttle for around $50 rnd trip, 1-2-3-Prague about the same as is discoverch.com. But then I found CEDAZ vans for $3.60 per person one way and Tourista Praha was the a few cents more? Is this possible? What am I missing?
