This is rather niche, but it works! Through December 31, 2020, if you have Caesars Diamond elite status, you can match it to M Life Gold, and from there, to Hyatt Explorist. I just did it this past weekend.
The only hitch is you must do the Caesars to M Life match in person. And of course, have Caesars Diamond status to start with, which is a free perk you get from FoundersCard membership. You can also get it from matching your Wyndham Platinum or Diamond status, which you can get from having a Wyndham credit card.
If you’re in a place where there are Caesars and MGM casinos or hotels, like Las Vegas, Atlantic City, or Tunica, it takes just a few minutes to get it done. I was at the Horseshoe Casino in Tunica, Mississippi, and walked over to the Gold Strike Casino. From there, I matched from M Life Gold to Hyatt Explorist online in under a minute.
Within Hyatt’s program, Explorist – the middle tier – isn’t all that different from Discoverist – the lowest tier – which also comes with having the Chase World of Hyatt card. But this is an easy way to get it for free and without completing a single stay.
