Thank you, the link is very helpful 😊.
Yes, more safe. Then to pick earliest train to olomouc the other day. Thanks for suggestions.
Yes, I’m going to book. Also its very good since Olomouc Hl.n leaves just 1.5 km from Palacky University, where I’m going, so thank you for infos!
There are trams from right in front of the main station (hlavní nádraží) in Olomouc - you used to buy the tickets on board, I think it is still the same, but you'll need some Czech coins.
Could I exchange euros to Kč on board and then pay trams?
No - there is no facility to change money on board trams. it is best to withdraw some CZK from an ATM in the railway station and buy a small item in the shop so you get some change - I am sure you can also buy tram tickets there.
