The headline really says it all. They have changed the name to better identify with the Caesars brand, but the only real changes aside from the name are:

• Platinum players and above receive 1 free night in Las Vegas or Atlantic City for every 5,000 Tier Credits earned in 2019 (up to a maximum of 7 nights).
• Diamond & Seven Star players receive 2 free nights at the new Caesars Resort Dubai.

Earning rates remain the same. Your account number remains the same. The daily tier bonus levels remain the same. Most tier benefits are unchanged. The Salute Card is still available.

I will do a more detailed post with the Caesars Rewards 2019 info soon.
