@AldoGordo I saw there was a question re: discrepancy on ferries earlier. This is an edited and expanded version of my original post. This is one of the reasons why, the Plymouth onwards part of the route, does not seem authentic.
This is them, in Plymouth, when the ferry has apparently got stuck on a sandbank:
".......we wandered aimlessly, finding ourselves in the centre of the city as the street lights were coming on. Past the shopping centre, then on through the university buildings.
‘Next month I’ll be part of that uni; now I’m walking through it without enough money to catch the bus.’"
For what it's worth - I think they're talking about the wrong ferry again and/or they're in the wrong place to get the one they want.
Plymouth Sound has huge Brittany ferries, and British and international warships going along this same channel of water constantly.
The short crossing for Mt Edgcumbe goes from Stonehouse - not the Barbican, where they are. (As another poster has explained, from 2017 in holiday season it does).
I don't understand how you can not have enough for the bus - but have enough for the ferry.
If they had asked, the other people waiting, they would have told them how to get on the bus and reach their next point - when you're on the bus, that will take them to Mt Edgcumbe, the Torpoint ferry is free.
They stay in Plymouth overnight. The next day they again they describe the Barbican, before going for the ferry.
