when I first went to bali all those years ago, they had those time share scams, where they give you a lottery card or scratchie which you always won,
Still doing it as of last month. Its not really a scam as such, just a cunning way to lure you to the presentation.
They do the same thing here, except instead give you a free DVD player or one nigghts holiday. I have been to a few and taken the free night. Its worth it for the pain of a 2hr sales pitch.
