Was looking at popping over to Dunoon at some point tomorrow and was checking Ferry costs.
For a Car, Driver and Passenger, its £36.20 Return if you pay it on the boat,
However, theres a newsagents down on Shore Street called Pauls Food and Wine. In there, they sell tickets for a car with driver and passenger for £19.20 return.
A saving of £17 for a roundtrip.
Hopefully it will be of use for someone! Im heading there tomorrow to get my cheaper ferry tickets! :)
