We have stayed at the Royalton Riviera Cancun a number of times, and we very much enjoyed our last stay. One thing we really love about the resort is the kids club. Our son, who is seven, enjoys hanging out there, and we enjoy the time to ourselves. All of the caretakers are friendly and kind. If you have children, you can feel comfortable and confident leaving them in the hands of Carolina, Alberto, Juanita, Lulu, and Mari.
Our biggest complaint was the food, as options have changed (i.e. no filet at the steakhouse anymore), and the quality, overall, was not as good as on previous visits.
We recommend this resort for both families and couples.
