Hello! The difference between the prices should not be more than 15usd, most of the properties in Mexico work with American Dollars, for example, in our property, the lowest rate this year was $209, next year, and the same suite will be $219us. And most important, if you confirm your wedding at any property this year, you will sign a contract give a deposit, and the rates stated on it will be valid for next year! Let me know if this information was helpfully for you. Regards, Tatiana Valdez
