You are right that it needs to be a joint effort, but I think the 2001 experience was a mixed one. Many people went because that was a unique thing, and in some kind of misplaced loyalty. I don't know anyone who would go to such an event again. When they got there, many found it pointless and boring.
Many people went to the 2002 TT because it was suddenly a novelty again. Many had bad experiences with expensive, poor quality accomodation, drunken, inappropriate entertainments, and the ferry, of course.
A lot were first (and last)time visitors, who didn't come back, because the new novelty, whatever it was this year, took its place.
However, a large percentage...the ones I know personally, were sickened by the above quoted rip offs.
Notice how the German visitors were down...a lot of them marshals etc, who have come for many years....how do you get them back?
Unless that the Isle of Man can build on ALL its attractions, and they are many, it will lose all its tourists, and when the financial whizzkids find another home, there will be a huge gap.
I am sure I am not the only person who, as a result of attending the TT in the 70s...at a lowpoint in its history...I have revisited dozens of times, and visit outwith racing times...(coming over next weekend!), because I love the Island for itself. I don't go to Jersey, Isle of Wight or any of the countless places I could...I love the Isle of Man, and I found it at TT time.
