I stayed at the RIU Cancun with my mom, toddler daughter and teenage niece. We all had an excellent time. There is not one thing that I can think of that was negative. YES it was hot but it is MEXICO in August. The room was perfect for the 4 of us, we really did not spend much time in there other than to sleep and get ready for our wonderful day's. it was AIR CONDITIONED, do not believe what others are saying about the non air conditioned rooms. YES the lobby is a little warm but again it is MEXICO in August, it would be very hard for them to keep this area cool as the doors are constanting opening and closing with people coming in and out. The food was great, enough variety for all. Always something for kids to have. A variety of different ethnic foods of all kinds every day. No compliants at all. Never had any issues with the staff. We had a small issue with our toliet shortly after we arrived and I called the front desk and someone was there to fix it within 15 minutes and it was 12:30 am. Room was always clean with fresh towels etc. The entertainment at night was refreshing. We enjoyed sitting and relaxing and being entertained whether it was dancing or singing. The organized sports at the pool were great too, always a good laugh while listening to the entertainment team. The pools were perfect for all ages, spent each and everyday at the pool. CLEAN each and every day! An EXCELLENT time guaranteed.
