Seedling Senior worked for a fornight at Portmerion in the hotel on the complex where the series was shot, last year. Had a great time, and was fully imbued with the Prisoner culture, on a loop in the hotel tele feed. Lovely place and have visited myself many years ago with The Venerable Mrs Seed. Well worth a visit, and if you take the most direct route, its a decent drive over the mountains! 3 Hrs ish
