In the SSI newsletter (as well as in email I received from TR), one month will have 5X TC and 5X RC; in AC "multipliers" were the norm several times month and particularly on holiday weekends--I assume AC players will get both

They also note RC expiration has been extended to at least 9/1/20.
All of this hinges on a timely reopening, many states are being more liberal than either Nevada or NJ.
These multipliers were becoming pretty common in non-Atlantic City markets too. I made the mistake of playing at Harrah's Ak-Chin once. Why a mistake? Because based on that one visit they started cranking out an insane volume of direct mail to jam up my mailbox... Ak-Chin was doing frequent multipliers per their junk mail.
Also noticed frequent multipliers of up to 10X on RCs on select Fridays/Sundays and (I believe) 5X on TCs at the Horseshoe SHV earlier in the Feb-Mar timeframe this year.
Louisiana is a decent size market for Caesars with Harrahs NOLA and Horseshoe and LA Downs racino around SHV. Believe that all gambling in the state is still shut down.
But I expect promotions galore across the Caesars network later this year. (Re)qualification will be easier than ever.
