The I-o-M steam packet co are total rip off merchants, you can take your whole family (granny, grandad, cat, dog etc) with a caravan, over to the island on non TT/Manx weeks for the same price as you and your bike during the racing weeks. I wrote to them and complained, said I wouldn't go again because of the ferry prices...... no response..... why should they..... they are fully booked every year, even with extra ferries.
