One of the first things I do when I check into a hotel in Las Vegas is put the "Do Not Disturb" door hanger on the door, just in case I collapse on the bed and fall asleep. I don't want anyone bothering me.
I've seen all kinds of hangers, but the one at the Luxor Hotel & Casino is very interesting indeed:
So what do they mean by "a lot of LUXing going on," and "getting our LUX on"?
Terrific double-entendre there, especially with the picture of the couple on the bed.
One would think that there's a lot of hanky panky happening when the door is locked, huh?
And "Lux" sounds like ... well, y'know.
Ahhhh, That must be what they mean by "What goes on in Vegas stays in Vegas."
