I play penny slots...of course you know that does not mean A penny :O)
I average about $2. per bet.
It is not about how much you gamble but how much goes through the machine. ALWAYS put your key card in to get tracked.
So....if I put in $20. & do not hit anything & walk away, I probably do not get any points.
If I put in $20. & keep getting little hits like $2., $5., $1, etc & play for an hour on that $20, I get lots of points because I have put a lot through the machine.
If I put in $20. & hit $1,000 on my first $2. bet & then walk away.....good for me but in less I keep playing, I will not have any points because I only put $2. through he machine.
You usually get the coupon by the 4th day on a 7 day cruise. It is really good PR because with a 1 year expiration date, I am sure a lot of those coupons go unused.
I have heard it is a lot harder to qualify if you are a table player but not really sure how that works.
