Hello, I am planning to make a trip in 2018 from june to august, but I've never been to Europe before and I have doubts. I made a map with the places and a possible order in which I could visit them. Do you think that's possible to visit the destinations within two months? Would you suggest a new order? From which destination a train can't be taken? Is any dastination not worth visiting? Thank you very much. Since I can't put the map up here I'll make a list in order with the destinations.
Dublin
Belfast
Edinburgh or Glasgow
London
Paris
Luxembourg
Brussels
Amsterdam
Frankfurt
Zürich or Berne
Monaco
Rome (Passing through Milan)
Ljubljana
Zagreb and the Balkans
Somewhere Montenegro
Athens
Sofia
Belgrade
Bucharest
Budapest
Bratislavia
Vienna
Prague
Berlin
Warsaw
Thank you guys for the help.
