On my last trip I had upgraded to a spa suite at Monte Carlo and had the resort fees for our 3 day stay. On the last night I went and talked to a host about getting the upgrade and the resort fees comped. I told him to use my remaining express comps about $60 worth left at that time and then asked for the remainder to be comped. He looked up my play and said no problem made a call and that was that. Easy breezy. When I checked my mlife account tonight I noticed that I have a $-164.00 express comp balance. I'm not sure if I have to dig myself out of a negative balance hole to start earning express comps again? I didn't get to play as much as I wanted this last trip, mainly because of the people I was with. (I guess some folks go to Vegas for other reasons than gambling.) yeah I was shocked also. I only managed to get 31,000 tier points this trips. Although I do know I was rated at $100 a spin on roulette a couple different sessions and some in the $40-$60 range. So is this negative express comp balance a normal thing?
