Less than 2 days to do this, but...

If you didn't use your entire $500 in food vouchers from your Seven Stars "celebration dinner", you can go to the Total Rewards desk at any property, and convert the remaining vouchers to their equivalent in RCs.

This is a great deal, especially for those who like using the RCs for things other than food.

You only have until January 31 to do this.

No word as to whether you can do this for 2018's vouchers (starting February 1).
