Just moments ago, I took this photo from my room at The Venetian:
Look at the windows on Treasure Island. See the shutters? See the little balcony thingies? Now count the stories. You should come up with something close to 17.
Next let’s look at how many rooms are on a each floor. The building consists of three slabs that meet in the middle. You can see one full wall of one slab in the picture, and you can clearly see that there are 9 windows.
There are two problems here. Treasure Island is a 33-story building, and the slabs are 18 rooms long.
The secret of Treasure Island is that each of those windows that appear to be a single window is actually the windows of four hotel rooms made to look like one. (Bellagio does the same thing.)
The obvious question is: Why? No secret there. It’s The Strip. It was done to make money. Which takes us to the next question: How does this optical illusion generate more profit than the alternative?
You’re on your own on that one. All I promised was a secret. I didn’t say anything about solving mysteries.
