Reviews Summary

Visitors often praise Sian Ka'an for its stunning natural beauty, abundant wildlife, and the tranquility of its lagoons and beaches. The opportunity to see dolphins, turtles, and diverse bird species is a major draw. However, some find the infrastructure basic, and access can be challenging without a tour, with road conditions sometimes being a concern.

"Overall Pleasant Stay – Special Mention to the Staff (Alexis & young lady at the front desk whose name I unfortunately did not catch)

Upon arrival, you may be asked to pay approximately USD 100 in municipal taxes/fees to the municipality of Cancún for the beach, even though my travel agency in Canada did not inform me of this payment in advance.

I also encountered an issue with my reserved suite. I had paid an additional fee for a suite with a jacuzzi and an ocean view, but I was informed that no such suite was available at that time. As a result, I spent the first night in a suite without an ocean view, which was disappointing given the extra amount paid. That said, I would like to highlight that the staff was responsive, took my concern seriously, and the situation was resolved the following day, which I truly appreciated.

I especially want to emphasize the excellence of the staff, who genuinely made a difference throughout my stay. A special thank you to Alexis, as well as to a young lady at the front desk whose name I unfortunately did not catch, but who was exceptionally kind, helpful, and professional. Their attentiveness, positive attitude, and sincere willingness to find solutions left a very strong impression on me. This level of service truly deserves recognition. (If I am able to retrieve her name, I will gladly update this review.)

Regarding dining, the food is acceptable overall, but I highly recommend choosing the à la carte restaurants rather than the buffets. The à la carte options offer better quality, more attentive service, and a much more enjoyable experience. There are more than seven à la carte restaurants, allowing guests to choose different cuisines and enjoy variety throughout their stay. In my opinion, these restaurants are one of the hotel’s strongest points, and I would recommend avoiding the buffets as much as possible.

I also appreciated the overall atmosphere of the hotel. The setting is pleasant and truly ideal for relaxation. The team, in general, is friendly, welcoming, and attentive, which greatly enhances the quality of the stay.

For guests who prefer to spend an evening at the hotel rather than going to downtown Cancún or nightclubs, the hotel regularly offers on-site evening entertainment. Personally, I really enjoyed the traditional Mexican music night and the pirate boat show, both of which were fun and well organized. A special mention goes to a tattooed young female performer during the pirate boat show she was excellent and truly made my night with her energy and performance. (If I am able to retrieve her name, I will gladly update this review.)

One final point worth mentioning: although my departure was scheduled for December 11, 2025, I was informed on December 10 that my suite would not be cleaned that day because I was leaving “the next day.” I raised this issue with the front desk staff lady, and it was quickly resolved, which I appreciated.

In summary, despite a few organizational issues, my overall experience was positive, largely thanks to the quality of service and the professionalism of the staff. I would recommend this hotel, and once again, thank you to Alexis and the lady at the front desk for their valuable assistance."

"WARNING DO NOT EVER GO TO THIS PLACE. We just got back from staying at the Sens/grand oasis and we are EXTREMELY upset and will never step foot in that place EVER AGAIN. What we thought were mosquito bites ended up being a scabies issue….after landing home, my mother and I became very itchy and started having skin flareups/ red bumps all over…. We went to the doctors and were told this was SCABIES from MITES. The only place we slept on that entire week was at the sens resort. I am disgusted and extremely pissed off. On top of coming home with SCABIES, we also just had a terrible time. Extremely long lines out the doors with over an hour and a half wait for ANY place to eat there. The front lobby staff were not accommodating at all. The beach was not in special, we went to visit another resort for the day and it was a completely different beach and so much more beautiful on the same strip these people were. Overall, this was an unforgettable experience and not in the best way at all. Please avoid this place and please listen to the reviews, I genuinely tried giving it a chance but never again"

Lilyana Nunez

"The hotel looked lovely in the lobby but we were ambushed by reps selling timeshares and covering the timeshare under the pretense of a free gift for my birthday to get us to the sales presentation we were hounded by the reps the whole time we were there.
The hotel was advertised as 5 stars but this was definitely not the case air con not working, tiles missing of the bathrooms, decor was dated and rundown, no towels in the room and no replacements when they were asked for.
Queues for every restaurant at least an hour each time we ate. Food was average and disappointing in most of the restaurants. Fully inclusive but with a lot of catches we would not stay at The Sens again.
The beach was clean and well maintained but was full of sales people all the time selling their wares.
Loads of building work all day and late into the evenings everyday of our stay.

Disappointing is how I would describe the hotel and it's services a shame really as Cancun as a destination is beautiful."

Exploring the Waterways of Sian Ka'an
