It sound like the kind of show that you would like to go too, laid back, friendly and full up.
Its a hard job trying to please everyone its even harder setting up a show and having the show comeback year on year.
Would it not be better to pass any comments on the shows make up good or bad through you're local MVT Area Secretary? From memory I seem to remember various letters / emails of congratulations being received by the Area Secretary in Manchester thanking him on behalf of the members for the turnout at various shows that members went too. I know the Area Secretary in Manchester asks for feedback so that it can be passed back to organisers, its more likely to be constructive that way.
