One spring I wanted to checkout the parks near Vegas: Valley of Fire, Hoover Dam, etc. But I stayed in Vegas because the cheapest hotels were there. Every evening, after a day of hiking, I would walk into a casino, sit down at the gambling machine, insert a $20 bill, and hit "drink service". A few minutes later a free beer emerged, and I promptly hit "cash out", collected my $20 and walked away (after a stop at the free popcorn machine too). I think I may have come away with more than 80% of their clientele.
