My parents get these free charter flights to small casino areas in Nevada (Elko/Laughlin) that fly out of topeka and make stops at other random small airports on the way.
Wait, what?
You have heard or "Churning" to get free airline miles with CC's right? My dad does that with Casinos.
Buy in for a hundred at the craps table, play some minimum bets for a while then cash out chips at the cage.
Take that same hundred from the cage to a different table and play for a while then cash out chips etc etc. At the end of the day the casino shows that he bought in for $1000 when he was actually using the same $200 all day.
The casinos in the Podunk NV towns are desperate for customers during the week and will fly you out and give you free rooms.
