Someone explained it to me on the VMB site, and it makes sense......sort of.
He said that the casino knows my history, and my comps are based on that. They give me three free nights based on the theory that they have figured out that's how long it takes to get my gambling budget. He went on to say why would they want me there if I am not gambling? It makes a little more sense when explained like that.
Here's the rub. My normal trip is 4-5 days. This trip is 15 days. Wouldn't a smart person figure I am bringing more money than normal? Even if I don't bring more cash, I am STILL paying for the right to stay at your casino. It's not like the place is going to be at 100% capacity.
Bottom line is that they are in the business of being in business, not me. They have a line on everything. You will see a casino with table after table of no one playing because the minimums are $50-100, while the two tables that are $15 are packed to the gills. You and I would think, "Why not lower the minimums on the other tables", while the casino knows they will eventually get players at those tables, and cover their nut. (I guess)
