"Grand Prize (1): A 7-day/6-night trip for two (2) to Costa Rica. Trip includes round trip coach class air transportation from major airport within a reasonable distance from winnerıs home and hotel accommodations (based on double occupancy)."
U.S. only. Ends 1/31/04.
They put the odds of winning at 1:1.5M - I think they'd be lucky to get 1/10th of that number of entries.
