Would you like an additional four return sailings each week, and a longer day available on the mainland next winter? Sailings that would enable you to get to Oban before 8am or 9am every weekday? Be able to get the 9am train from Oban and be in Glasgow by 12 Noon six days per week? Have 6pm return departures available every week day?
