I've been to a casino, to check it out, even though I don't gamble. What I was most impressed with was how there was no clocks, no windows, and everything was open 24 hours, so there was no way to tell the time.
I'd love to stay at a non-gambling resort like that. A "Timeless" Resort, Literally. A way to put yourself in a world where you don't keep track of time, and can go get food, or drinks, at any time you want. Sleep when your tired, wake up when your done, forget about the sun, and the clocks!
