This is from today's LVA Question of the Day. For all the bashing their new website has received (deservedly so) their QOD is often interesting. https://www.lasvegasadvisor.com/question-of-the-day/ This link will bring up the new QOD so if you click on it after today you'll get something different. So I'll post it below. Two different answers depending on if you combine Ven/Pal and Wynn/Encore ________________________________________________________________________________ And the prize goes to … Venetian, which sprawls over 243,684 square feet. This presumes you count the contiguous Palazzo, which shares the same gaming license. It’s a similar case at second-place Wynn Las Vegas which, when Encore is includes, embraces 186,187. (Again, the two casinos share the same casino license and flow seamlessly into one another.) If you counted Venetian and Palazzo as discrete casinos and do the same with Wynncore, the winner would be mammoth Mandalay Bay, so spread out you practically need a golf cart to traverse it. Its footage is 160,344 square. In fourth place is Bellagio, at 159,760 square feet, which you might expect, but the fifth-place finisher will probably be a surprise to anyone who doesn't live in the far north of the valley: Santa Fe Station, which has grown over the decades to 156,401 square feet. MGM Grand only weighs in at sixth place, even though it seems like you need to pack a lunch if you’re going to cross the casino floor. Its official square footage is 156,203. Right behind it is South Point, the three-towered locals casino that rounds off its square footage at 151,000. It’s even bigger — by 1,000 feet — than Aria, perhaps because Aria’s amenities are “stacked” and South Point’s aren’t. Boyd Gaming’s flagship property, The Orleans comes in at ninth place, for a relatively slender 137,000 square feet. Rounding out the top 10 is Station Casinos’ Green Valley Ranch, which sprawls across 134,681.
