I’m liking the ferry ideas.
Got a provisional 300 + 175 route from home, hitting the coast near Maldon then shadowing the coast as close as possible subject to suitable roads, and hitting the beach here and there. There’s a seal spot north of Gt Yarmouth, so I’d like to hit that. A Premier Inn Lowestoft, £30, on Sat night then finishing on Sunday afternoon at Kings Lynn. Then train Kings Lynn to Cambridge and home.
I’m thinking midnight Friday start from home giving a late afternoon/ early evening arrival in Lowestoft. A full relaxing evening and sleep in Lowestoft. Then a 7am start or so, after breakfast for the second leg.
All subject to nights away still being allowed of course.
