Thanks for the heads up.
There is, BTW, a Travel Sweepstakes forum under Travel & Dining.
As to zero, you can't win if you don't play. As someone who has won a trip to Paris from our PBS station, 2 AA tickets in the US from Nissan, and a trip to San Fran. from Starwood, I'll be playing.
So, thanks, to any of you who don't want to play -- improves my odds!!
