I have very little play at the Las Vegas properties, but I have quite a few rewards credits from a mix of play at Harrah's Rincon, dining/shopping at the Las Vegas properties, and Social Rewards. I'm not diamond so I don't get an automatic line pass for the buffets. Can I go to the TR desk and ask them for a voucher to the buffet (I would "pay" with my rewards credits) and use that as a line pass? I have done that in Rincon, but have not tried it in Vegas. Since the Vegas properties have a paid line pass option ($10-$15 I believe) would they want to charge me rewards credits for that line pass?
