Planet Hollywood buffet coupon, all-you-can-drink for $12

The buffet at Planet Hollywood Hotel & Casino (which is still the same Spice Buffet from the old Aladdin) has an offer if you check-in on Foursquare — buy 1, get 1 free.  Just show the “coupon” on your phone to the Total Rewards desk, and they’ll give you a coupon to use downstairs.
In addition, PH has a front-of-line pass for $12.  Sometimes it’s worth buying your way to the front of the line.  Note that Diamond and Seven Star members can cut to the front of the line anyway.  Even if there’s no separate line (as we saw when we were there), just wait at the front and flash your card.
And a new one: $12 extra will get you all-you-can-drink beer and wine while at the buffet.
