I'm a bit confused by the description of the Irish Rover Bus Pass. Has anyone used it before? We're using the bus to make three major "jumps": Dublin to Galway (stay for 2 days), Galway to Portrush (stay for 3 days), then Portrush to Dublin. When the website says "Valid for 3 days out of 6", do those 3 days of travel have to happen consecutively, or can they be used in a situation like the one I describe above (used one day, wait 2 days, used again, wait 3 days, used a third time)? Any input is appreciated!
