So... 1st weekend of march, a return to Oban is £61, two singles to/from Oban is £25, and two singles to/from Arrochar is £32??
I'm not complaining (unless they try to charge me more for disembarking at Arrochar) but what's going on? Is this a cunning way to get £61 quid out of people who (understandably) assume a return is cheapest?
