umm...you've marked the Wynn Hotel in Las Vegas as one of the world's tallest hotels (which it probably is). However, your place mark is in the wrong spot. You've marked the Frontier Hotel, actually. Wynn is across the Strip from the Fashion Show Mall in the big empty lot (apparently, it hadn't been built yet when this satellite was taken). Some brainiac has marked it "Dessert In" there...but the placemarket 'the Dream' is accurate.

Just wanted to let you know...
