Great post, Dan -- you said it perfectly.
Money -- As Dan said, it is my prerogative to play or not play when I take an offer since it is given to me based on past play. If I want future offers I will play, if I don't want future offers from that property I won't play if I don't want to.
However, by not staying there and being double triple booked the casino is also not paying out on all components of the offer as I might not use their dining credit, free show tickets offered to me, etc... And if I put a friend or family member in the room then they also have MORE people to shop, gamble, and dine in their hotel/casino, so they benefit even more.
Let me just give you a quick example: One of the places I'm booked at is Four Queens. They only require $10k coin in to receive the mailer that comes with $200 free play and all food (with one dinner at Hugo's) . This offer is for 3 nights. I could stay the three nights and eat three meals a day there, use my $200 free play and give them $10k coin in, or I can do what I always do and book the offer for two nights, eat one dinner there, use my $200 free play, and give them my $10k coin in (sometimes more -- last time it was $25k). If none of my friends or family wants to use the room I will check out after dinner or the next morning so they have the room to sell to someone else. And if there comes a time when I no longer care about receiving this offer I might very well book it and not give them the whole $10k coin in. But that is my prerogative and they will answer me with a lesser offer or no offers.
You really need to take a step back and look at what you're saying here.
