Jul 14, 2025So much to celebrate
We had such a fantastic time at the RIU Dunmar! Special shout our to Anya at the buffet , Santiago at the Sports Bar and Rene at the swim up bar you guys all went above and beyond! Everyone was so nice and welcoming to our large group. My only critique for RIU in general is there really needs to be a band color in between kids and adults for your 15-17 year olds that are there with an all adult family who do not want to hang in the kid pools but those older kids can't get in the swim up pools.

Jul 08, 2025I recommend RIU Dunamar
Great service, friendly people, good food, enjoyable entertainment, children pool and slides, nice beach (disregarding the seaweed that was present when we were there) and lovely touch with decoration, balloons, a card and deserts in our room for my son's birthday. Thank you !

Great Activities for families!
We visited this resort with a family of six. I purchased four connecting rooms. Rooms were well cleaned. They do not restock the refrigerator. However, it was unnecessary due to the number of rooms we had. The activities were a 10/10. My children ages 11, 14, 18, 20 all participated in various activities, such as beach volleyball, water volleyball, Riu Fit, Salsa dance class (my favorite :)), Yoga class, jet skis, and use of boogie boards. These were not all of the activities, there were others such as ping pong, beach soccer and activities for small children that we didn't get a chance to participate. The resort is fairly large. The beach has crisp blue water and nice sand. There was a lot of seaweed, but it did not bother us. The view of the blue ocean was amazing. The water park is amazing, and my children spent the whole day enjoying the various slides and alternating between the three large pools. I did not rate this property 5 stars simply because of the bland food and drinks. Even the fruit juices taste more like a powdered fixed drinks instead of fresh juice. I really wanted to enjoy the food and drinks after having such a great time, but no matter the bar or restaurant it was all the same. Oh, the premade meals in the Sports bar were not very pleasing. We made it in at midnight from multiple delayed flights and I was anticipating a quick snack for all of us. Unfortunately, the food in this restaurant was not too appealing. Will this deter me from attending this resort again? Probably not. We really enjoyed the activities and that is what really mattered to my children. The property was well maintained and there was great customer service.

Jul 07, 2025FEELS LIKE PRISON
This is the worst place I’ve ever been in my life! I’m crying as I type this feels like I’m jail! ABSOLUTELY NOTHING TO DO. Here for 7 days with my poor kids who are bored to tears! I feel so bad for doing this to us . All you do is swim and eat( the food is the same damn menu every single day!!!!) like what?? No entertainment . Nothing to do or watch on TV ! This place is a joke lol. Huge joke! DONT DO THIS TO YOURSELF! I don’t know where this 5/4 star reviews are come from lol. I’m on vacation I can’t even get room service and pls it’s not that cheap! So yes at least room service some entertainment and food options… I have tried to rebook our flight o leave earlier than planned cos this is hard on us all. Bored to tears , hungry and angry! First day I knew this wasn’t gonna be good, Ricardo at the reception treated us like trash! EXTREMELY RUDE and comfortable about it because he knew nothing would be done of course ! He was so condescending. Like I’m so sad . I just want to leave this place . Truly unhappy here! I have 5 days to go and I’m depressed. This was supposed to be a fun family vacation we are all tired! Hungry it’s so unfair I can’t out it in words. STAY AWAY FROM HERE!! Pls !

Jul 07, 2025It’s fine……
This hotel is fine. It is not 5 star but it also doesn’t warrant the terrible reviews I have read about it. My husband and I travel to Mexico a few times a year and prefer adult only resorts but this time we traveled with our two 10 year old granddaughters. We got a family suite and very glad we did so we did not have to share a bathroom and the connecting door allowed for some privacy. It was also very quiet in n the room. The hallways of the resort are quite noisy due to design but we had no issues with noise in the room due to our location. Third floor facing the water park. Rooms are clean and they keep them well stocked. AC worked fine, not as cold as we would have liked but others will likely find it fine. Water in shower is very hot but pressure is pretty low. As far as food, no one will go hungry. All restaurants will get the job done. If you are coming here hoping to get a little tipsy, you will be hard pressed to get that at this resort. Drinks are very limited on alcohol. They do have Tecate or Dos XX in the can but you have to ask for it. If you prefer a less sweet margarita, ask for them traditional. They only have Pepsi and not Coke products. We usually travel to the Cancun area between November and the end of April so we were not prepared for the lack of breeze. It both keeps the bugs away and helps to keep you cooler. No such breeze during this time of year so very hot and pool water is very warm. Like very warm bath water, not much of a respite from the hot sun. Adult only pool with swimup bar does offer shade which is nice and Willy at that bar is great. The RIU brand is solid and as long as you go to this resort with realistic expectations you will have a good time. This is not a resort for those that want quiet.
