Palace Resorts in Mexico is offering a $400 airfare credit when you book a stay at one of their 11 all-inclusive resorts in Riviera Maya, Riviera Nayarit or Cozumel. To get this windfall, you must book by Dec. 15 for travel through Dec. 31.

How does it work: The airfare credit is based on the amount of nights you stay. Guests who stay three or four nights will receive $100 and those staying for five or six nights will receive a $200 airfare discount. Guests staying a week or longer will receive the $400 credit.

Why we like it: Who couldn’t use a $400 discount? However, another great perk with this resort chain is the ability to combine promotions during the same booking and travel period. For example, you can book the airfare discount offer and combine it with a spa or golf credit.

If you’re not sure which resort to choose from, consider that each location offers something different. For example, Cancun Palace is located in the bustling hotel zone, while Moon Palace Golf & Spa Resort offers luxury and couple-friendly amenities.

We searched a package from Fort Lauderdale to Cozumel in October. The $400 discount was applied at the end of the transaction for a total of $1,117 per person at the Cozumel Palace.
