tl;dr: How long exactly are Italian regional train tickets valid if I interrupt my journey at intermediate stations?
I have an Italian regional train ticket and it says
Vale 6 ore da convalida
i.e. valid for 6 hours from validation.
Q1: Does that mean I can take any train with a scheduled departure within those 6 hours or that I should take a train that (at least on schedule) arrives within those 6 hours?
Q2: Can I interrupt my train travel at an intermediate station (i.e. get off, walk around, take the next train) as long as both trains fulfill the requirement of Q1?
The typical example for this would be a tourist to the Cinque Terre, getting a ticket from La Spezia to Levante and interrupting his journey for an hour or two to see one of the villages of the Cinque Terre.
