I am trying to check trains to Rome, Florence ,Venice and Milan. I checked Rail Europe for buying ticket by ticket for destination., In that website I found cheapest tickets. But when TO make sure, I check it in Trenitalia, dates and prices that I am looking are sold out , and the prices are higher. How is possible that Rail Europe has cheapers that the train company ? DO I have to trust these website or not ?
Thanks for your advice !!!!!!!!!!
