We recently had two nights on the Island. I said to SWMBO, with what it cost, it wasn't worth going for one night.
I know nothing about the economics of running a ferry service so should probably keep me gob shut. (also I get irritated when people who know nothing about my trade, moan about what I charge) But why is it so costly? You can get over to France for less (I appreciate that route is on a much bigger scale and the freight fees probably subsidise the trippers)
We booked ahead (two people and a small car) and it cost is 120 notes. (including our senior discount)
We liked the island, but at that price would probably not come again.
