First time interrail. Is this a good plan? From italy to: Vienna, Prague, Berlin, Amsterdam, Paris, Lyon, Italy. I'll stay three days in each destination, except for italy, for a total of 18 days. I will sleep in hostels. Should i go for something easier? Am i not considering some beautiful country? I've just seen Paris and I'm not sure if i want to return there. I'll get the global pass (7 days in a month).

I appreciate every suggestion.
