Just came back from RIU Dunamar Mexico. Spent 10 days there (July to Aug 2023). Worst ever RIU I've stayed so far. Will not recommended nor will go back. Poor management, inconsistent service, bad customer service, favouritism towards locals, unfriendly, unwelcoming. 90% of the guest are locals. A lot of garbage left overnight at the beach, never picked up, lounge chairs were not cleaned up. Entertainment stage is located in the middle of resort, so you will hear all the noise, loud music, screaming people until it is over, no matter which part of hotel you are staying in. Food is repetitive, no themes, over salted most of the times, meat is overcooked. You will not be hungry, but nothing spectacular or memorable. Desert is boring, looks like chef has no idea what to cook for desert. I am a fan of RIU chain, but this one is decadently not in my list. Very disappointing experience.
