We are staying near the train stations in Krakow and Prague so thinking taking the train is the easiest way to get to Prague from Krakow. We are going in September. Looking for recommendations on which train to take/book. Railninja came up with a route I think we should take - it's a high speed train. Do I have to book through Railninja? I'd rather book directly with the train company (Czech Railways) www.cd.cz - opinions of which website to use? I don't like to use third party websites like booking.com for hotels - I'm thinking Railninja is like Booking.com, correct? We haven't taken trains very often in Europe - usually fly.
TIA
