I hadn't heard about this before and just happened to stumble upon it, so sorry if it's old news.
Apparently you can get a year of Wyndham Diamond status no strings attached as a MasterCard benefit, must request the status by 12/31/2024.
I went to
https://redemption.mastercard.com and signed up using the info they asked for (email, phone, card info -- I used my Citi Prestige FWIW). There are some mediocre offers that will appear, but at the bottom is the Wyndham Diamond offer.
HT appreciated if this is new news
