I just used it, and had quite a problem using it. Easy to lose $100 and get the play credited, but difficult to us the free play. First, you can't use it on a progressve, which takes some of the better VP choices. Next, you have to find a machine that is supposed to work for free play that actually will work on the free play. I went to a half dozen machines that told me my PIN was wrong or gave other error messages. I went back to the player's club (for my 3rd time standing in the line) and was told that "a lot of the machines don't work, you have to keep trying different machines until you find one that works". So I started systematically goingdown the lines of VP. After 18 (yes, I counted) trys I was told my PIN was locked and I had to go BACK to the club (4th time in line, and when I tried to symply ask, I was told I would be ignored as I didn't stand in line). When I got to the counter I was told that yes, the PIN will lock is there are too many tries in too short a time frame. I asked if I could be directed to a machine- any machine- that would work, the answer was a simple no.
I finally found one that worked and played all of the free play right there. Came out slightly negative, but not too bad.
The experience was bad and reminded me why I stopped going to Terribles. I tried to double up by using a 2-4-1 for th breakfast buffet, and was disappointed in thath as well.
If you have the patience and or the luck, the MRO is a great coupon, but I would suggest being prepared.
