I'm usually a poker player, but the last time I was in las Vegas I ended up playing a lot of slots. This week I received an email for 3 comped nights and a slot tourney invite to venetian. The fine print states that I will be required to maintain a level of play consistent with past visits. How strict will they be about this? If I put a few hours in will that be good? I'm guessing the last time I put about 6 hours split between penny, quarter and dollar machines over 3 days.
