Hello,
https://abetterrouteplanner.com/?plan_uuid=0c414f31-d3a8-42e9-b726-7c67b7e33eeb
Trip from the UK to France via ferry.

I've added the Portsmouth to Saint-Malo ferry route, per instructions, but the planning also adds more (redundant) ferry trips via Poole-Guernsey, Guernsey-Jersey, then (after charging in Jersey) takes me to Saint-Malo, back to Portsmouth and FINALLY takes the Portsmouth-St Malo ferry route
