If you are disciplined, you should use the player's card in most situations.

I will say this, however, in defense of Rob's attitude if not his instructions -- I have noticed more and more LV casinos, such as the Palms, are not only making point earnings tougher on the better payback machines, but they are actually excluding these machines entirely from all promos, even the small daily drawings. So folks who want to feel as if they have a shot at drawings and take-home minor trash have to make the decision to play inferior payback vp. Playing the better machines at the Palms is in essence the same as not using your card. You derive nothing from it other than providing the casino with your profile as someone who knows how to play.

My point is that this is the direction in which slot clubs are headed. If you play the positive machines, you may as well not use your card. There is no point to it, and you may actually be hurting your offers.
