For those of you wanting an update on the new Riu Dunamar, looks like it is slated to open the first week of December 2017 and is expected to be close to fully operational upon opening date. I originally had some questions as to its location, and from what I can gather it is situated north of Secrets Playa Mujeres more towards the end of the peninsula–next to Secrets is the new Palladium that is being built. While Riu Dunamar is listed as being in the municipality of Isla Mujeres, it is not actually ON the island of Isla Mujeres (which is a ferry ride across the sea). The new Riu is supposed to be a doable walk from the public beach area of Isla Blanca where winds are relatively stiff and kiteboarding is popular.
I just returned from another trip to Cancun and stayed at the beautiful Dreams Playa Mujeres Golf and Spa Resort during Feb. 2017. I stayed in an upgraded Preferred Club Jr. Suite Ocean View, room #7408. I had pre-requested a pool view in addition to the ocean view since I did not want to look out at the side of the resort and this wish was definitely met. This was the view from my balcony with its own comfortable day bed and Jacuzzi tub.
