Dwayne- yes, that perk is going to definitely get used (I will most like get Lisa to go and get her "entry" for me to use also :-) And yes it will be the black jack tournament and not the slots.. I have watched that multiple times and just don't see how it can be anything but luck. If they did a video poker slot tourney, I'd go for that...
You are most likely right about the slot tournament. They put the machines in another mode of operation for it. In regular play mode the slots do involve some skill and knowledge of pay ratios though while deciding on a machine to play. That's all I'll say about that.
They'll have a list at the casino cage of VIP's entitled to complimentary entries in the tournaments. They will ask for your S&S, and give you a ticket to give to the casino host.
