"email us for a chance to win a free trip to Switzerland"

A chance to win is not enough motivation for me to actually write the email. I would assume it was simply an opportunity to collect email addresses, so I (personally) am not to likely to email them even if I did fully read their privacy policy.

The fine print itself needs fine print, without any more details I'd assume that I have to pay for the plane ride there and they give me the crappiest hotel.
