Subject: Italy Flexi Rail Pass
sorry, but that's the wrong comparison criterion. if a kilometric pass is the cheapest alternative (and in this case it is, costing ~100us$ for the two people vs the $150 of point-to-point tickets), who cares if you leave 1/3 of the kilometers unused? that's irrelevant. put the name of an italian friend when you buy it, and give it to him with the unused km before flying back to the us...
