    Just ok

    The food was very subpar at the 3 restaurants. Quite a letdown. Thank goodness I got such a great deal otherwise the rating would get even lower. The employees saved the trip.

    Wonderful Family Vacation at RIU Palace Costa Mujeres! 🌴

    We were originally booked at the RIU Dunamar, but upon arrival, we were offered an upgrade to the RIU Palace Costa Mujeres for a suite — and what a great decision that turned out to be! My wife, our two kids (9 and 12), and I had an amazing time. The hotel is absolutely beautiful with top-notch accommodations and amenities. There were plenty of food options to choose from — whether you wanted a sit-down meal, buffet, or snacks by the pool, everything was delicious and fresh. The entertainment staff kept the energy up all day, and there was always something fun happening, from games and shows to the nightly events. Our kids loved the waterpark and the fact that there are six pools, including two adult pools for some quiet relaxation. The silent disco was such a fun surprise — a definite highlight for the whole family! The only downsides were a temporary power outage (which wasn’t the hotel’s fault — it affected the whole area) and the mattresses, which weren’t the most comfortable. Overall, this was a fantastic trip — a solid 9/10 experience. We’d absolutely recommend RIU Palace Costa Mujeres for families looking for a mix of relaxation, fun, and great service!
