I enter competitions like no ones business, but just had a call to say I've won a holiday for 4 people to either Portugal, Costa Del Sol or Tenerife. They pay for flights and luxury accomodation and I just pay booking fee of 29.50 pp and airport tax.
Company is http://www.lacosta.com.
I have to go to a presentation where I get my booking details etc. Looking at website, seems all above board but always a little wary ha.
