I have a mlife account and have just booked an offer through there site but I never have used my card while playing. I believe my hotel bookings have my card linked with them but don't bother with anything else. Should I? I bet small. I may buy in at a Roulette or BJ table for $50-100 or so. Is it even worth it? What will it get me? I do bet a little more on sports. Can I still use it? Again my bets are fairly small. $50-200 or so.
