I have travelled from Munich to Prague and return... For Prague from Munich - It's better use bus than trains. As buses are chepper in cost and taking less time. So it's saving your time and money as well.
Flixbus are proving great service and english spoken staffs as well... cticket booking ounter staffs are very helpful and gentle nature... pilot of bus also very very helpfull. Best part is it's safe and secure service, they never over speeding, you feel very comfort and relax during whole trip.
Only one issue you will face that free Wi-Fi are very limited... it's will give you excess net up to 150mb only also Wi-Fi not working in some the buses.
One more good thing that they keep plying English songs at low volume, it's make your trip more pleasant.
The best place to seat is top roof to get beautiful view and better if got front one at top driver seat. Roads between Munich to Prague are very good and natural views are amazing... that give you a great experience of Europeian forming fields both side of roads.
So at end I can say that flixbus service very good at convenient price. In future it's going to ply very big roll in Euro trip..! As trains are getting costly day by day.
