I have just booked me and my car to visit TT 2009, £313, about £13 more than last year, so not so bad.

However in filling the internet forms at first, I got a quote of £192 and then realised that this was the return fare on the same days as I wanted, but going off the island and coming back, £100 difference !!

Surely the ferries use the same fuel either way. How do they qualify the difference ??
