There are three World of Hyatt promotions for bonus points and miles you can use for December 2018 stays, but you had to register for two of them by November 30.
That is kind of a drag for an offer like 1,000 AA bonus miles per stay when the registration date ended less than half-way through the promotion period.
- World of Hyatt double points for MGM stays Oct 1 – Dec 29, 2018 registration link.
- World of Hyatt 2,000 bonus points for extended stays of 4 or more nights at Hyatt House Nov 1 – Dec 31, 2018. Note: promotion registration ends Nov 30. Maximum 30,000 bonus points.
- World of Hyatt 1,000 American AAdvantage bonus miles Oct 15 – Jan 31, 2019 registration link. Note: promotion registration ends Nov 30.
Basically you can still earn World of Hyatt double points for MGM stays if you plan to be in Las Vegas over the next two weeks, unless you registered for one of the other World of Hyatt promotions before December.
Now there are twice as many reasons to visit Vegas. Earn double World of Hyatt points on eligible spend when you stay at any participating MGM Resorts Destination in Las Vegas from October 1 to December 29, 2018:
- MGM Grand
- The Signature at MGM Grand
- Mandalay Bay
- Delano Las Vegas
- The Mirage
- Park MGM Las Vegas, formerly Monte Carlo
- New York-New York
