This hotel was NOT up to our likings. We stayed in the Royal Beach Club Room and and it was not cleaned very well. Also, the maid left room after she was done and never shut our hotel door. We returned to the room hours later, likely we put our belongings in the safe.
Also, someone opened our hotel door in the middle of the night( 2 times) and one of the staff members claimed it was a mistake! Likely we had the sliding lock on our door so they were unable to enter our room.

I would not recommend this hotel to anyone. We are starwood members and we ended up switching hotels after two days of staying there to the Le Meridian. The Le Meridian treated us like royalty! That is the hotel to stay at!

We are a well-traveled family of four -- two teenagers (14 and 17) in tow. We booked through the JetBlue website and have never been to Cancun, although we have been to Cozumel.

We stayed in the Royal beach club, a separate building from the main hotel, over Presidents' week. Our room faced the lagoon and was large, clean and well-appointed. It has the Westin features including comfortable beds. The ac was not functioning (the unit circulated air but the compressor was clearly not working) when we arrived but as it was 1 AM when we settled in, so we waited until the next day to get it fixed. We also needed a rollaway and were charged more than expected per night. Those were the negatives and we could easily overlook them considering the way we were treated throughout our stay.

I showed my Starpoints card upon arrival and we were told they hotel would comp breakfast and the happy hour. There is no other place to eat nearby so we saved money and time with this deal.

I cannot vouch the rooms in the main part of the hotel which seemed to have been assigned to two different conferences that were held during our stay. Our room included an electronic safe, bathrobes, and plenty of towels for the four of us. It was large and there was a balconey with a table and two chairs.

There are a number of pools of the property both on the ocean side and the lagoon side. I walked quite a length of the beach and it appeared to me that the Westin beach was one of the nicest. It is wide and there are many chaises with umbrellas and other covers. Some early birds claimed seats but there were enough shaded spots to go around.

The breakfast and lunches were fine; it is a resort so the lunches we ate by the pool were not cheap. The selection of food at lunch was wide enough so my picky eaters always found something.

This is a relatively quiet place, closest to the airport except for Club Med. Groups did get some volley ball going but the well-known action is further on up, not here. Bus service is frequent and very cheap. If you any bit adventurous you can get around without renting a car or using taxis. My teens said they enjoyed the bus rides the best. One South American group of teens got on at one of the hotels and immediately began to entertain themselves by singing -- this is what my kids remember.

The hotel will suggest and book restaurants -- some have been mentioned in this thread. I would also suggest that you change some money into pesos before you get there so you can tip staff when you arrive. Cancun lives by tourism and good service should be rewarded.

My teens have both said they would go back to this hotel in a minute -- I would say that sums it up for us all.

We stayed at the Westin Cancun with our 3 children 5, 4 & 2 yrs old. We upgraded to the Royal Beach club rooms which included at breakfast buffet and happy hour with apps buffet in the evening. We found this great for those with kids because we did not need to wait for ordered food in the restaurants and the kids always got a good breakfast with lots of choices. Yes, the eggs could be a bit runny but they also served bagels, cereal, fruit, pancakes or french toast...lots of choices. The evening was hit or miss for the kids but no big deal it was nice to have the option. Our room was fine, we did not really spend time there except to sleep..no dresser for clothes, that was a little strange. The cleaners were sweet and our room was always clean no problems. The beach was clean and beautiful also 8 pools ot choose from. We never had a problem finding chairs. There are some children there but not so many that it is a crazy kid fest (even we do not care for that). The servers were fantastic, Marco was our breakfast server every morning and was so sweet, helpful and friendly. Bernardo and Juan were our servers on many occasions and were both terrific, friendly and very hardworking. The entire staff was hardworking and great. They never stop cleaning everything. I was so worried when I read the bad reviews..I had nothing to worry about. I understand that some times people will just have bad luck with a place,others are hotel snobs. The Ritz is right down the street if you want to pay the price. We were really happy with our vacation experience at the Westin.

Cancun is like Miami beach, just as built up and expensive. Haven't been here in years and now there are 80+ hotels and 30000 rooms, the old charm is gone. Stay in Miami instead.
