Hyatt is offering 2500 United miles per stay, targeted at United elites, through January 31, 2011. Registration required.

As with so many of these promotions, they say “United Airlines® Mileage Plus elite members are invited to..” but the terms and conditions do not say anything about a requirement to be a United elite to earn the bonus. Hyatt doesn’t know whether the participating member is a United elite or not, it’s just that’s who is being marketed to for the offer. In my experience these bonuses generally post for all members, regardless of airline elite status, but one has to test it and see for sure (though if you also comb the terms and conditions of the offer, verify there’s no mention of United elite status, and print that you would likely win an argument if for some reason the miles did not post).
