Great hotels have great swimming pools too, that cost huge amounts of money to build, staff and maintain. Yet those are free to use, at least for guests. Why don't they shut down the pool and use the space for slot machines?

What about the fountains at the Bellagio, or the waterwheel in the conservatory? I am sure the Bellagio could make more money on a balance sheet by shutting those down and putting in slot machines. Yet they don't, and, surprisingly, the Bellagio is very successful.
