I'm having trouble finding the answer for this question. According to total rewards. No one but you can use your card. We often played either my wife's card or mine simultaneously to rack up comps. I have never tried to play more than 2 at a time. I'm a hypothetical situation...what if I had 4 cards with my name on them and and let the rest of the family use the other 3. Excluding hand pays (that's where I'm pretty sure someone else playing my card might catch some heat, I might loose my privileges ect...idk whatever) would this be possible and has anyone ever done it? If this has been answered on this forum before please post a link to the correct post so I can read it. I can't find it Thanks in advance.
