update the Wyndam Rewards Earner Business card from Barclays worked again to match me to Diamond status.

Took about a month from online matching on Caesars website but it worked. You get the $100 dinner for Diamond which offsets to credit card annual fee of $100 or so.

I guess you have to have a business but I use the card maybe once a year. Also, you can transfer all your Wyndham points to Caesars with no penalty (that I can tell), so that got me another $400 or so in comps.
