One Window Four Rooms

This shot clearly demonstrates the one window for four rooms trick.

I'm not sure why this is done. I can think of two reasons. To shrink the building (visually) so it's less intimidating (seems closer, less perceived walking distance) and simply as an architecturally more  pleasing design.

The Bellagio, a 32-story building disguised as a 16-story building.

Same here at Treasure Island.

And again at Caesars (three floors, six rooms).

Wynn uses one white stripe for every two floors.

The Monte Carlo does not use this trick. This building is the same size and shape as Treasure Island (above) and has a large, cluttered look. One reader calls it a "maximum security resort"
