I've been receiving the Las Vegas only offer weekly but hadn't opened it until the one I received today.
The email subject line read "Here's Your Ticket to Earn 1,000 Tier Credits When Booking With Us"
There seems to be two promotions offered the "New Year New Empire Sale" (NYNE18)which you receive a discounted rate when booked by Feb 19, good through Dec 29.
The Rio has a different code RBOU1 and includes a coupon for a bottle of alcohol.
Here's the fine print:
