I will be going with another person one-way from Warsaw to Venice next summer and can't quite decide on the best way: by air or by rail.
By rail seems to be the cheaper option, but I'm very inexperienced with European trains and have found several different websites, some that encompass multiple countries and then some that are country specific. The prospect of a train trip is exciting and I don't mind an overnight trip.
I have looked around and done some research but I'm having trouble finding actual advice that isn't from the businesses themselves who obviously want people to book with them. I'm just looking for some advice from real people unaffiliated with the rail companies who have traveled in the Poland to Italy region.
