were comped, tried to comp all of our stay (4 nights), but we had priceline prepaid the room. With 10k in points, we were gladly assigned a slot host, who quickly let us know that all food and bev. you do lose, but from a points perspective, you can get far more points than just the dollar amount would make you think. The quick math is that once you put in the wins, we played 10k worth, with only physically investing 2,000. we wagered or played enough 'bets' on the slots to equal 8,000 points for my wife, and 2,000 points for me.
Long story short, a point on the card is roughly one dollar wagered (won, inserted, whatever). lost about 1300 once you took comps and hits into account), but she must have hit more wins than I did. We both gambled similar amounts (about 2k total before any wins are factored in. We were in Vegas 6/17 through 6/21 recently and used the MGM/ Mirage Players Club Card on a linked account between my wife and I.
