Win a 12-Night Trip to Europe with Accor Hotels

How does a free trip to Europe sound? Hitting up Paris, Berlin, and Barcelona with roundtrip airfare, 1st class train tickets, and all hotel nights included? Accor Hotels is currently running a contest with a pretty nifty grand prize; the 12-night European vacay is valued at $11,000. Get your game on with the "Around the World Photo Hunt" and you could win it. Here's the skinny on the online game: simply click the four differences in the two (seemingly identical) photos before your time runs out. The photos depict different Accor properties around the world. Even if you don't snag the grand prize, you could end up with other cool things: a luxurious SoBed package including a mattress and box spring by Serta, a featherbed, a duvet and 4 pillows by Pacific Coast Feather (valued at $3,830); a Samsung HD LCD TV; home-theater system; Bose Wave Music System; Nikon digital camera... (the list goes on.) The contest runs until July 23rd and is offered only in the United States.
