We just returned from staying at the JW Marriott (7/20-7/28). The Hotel is awesome and the staff very accomodating. The food is excellent, pricy, but well worth the price. Only drawback is that after the 1st day, when I specifically inquired about the "Sea Lice" I was told no problem this time of year. I went into the water and received a rash the very first day that I still carry with me 9 days later. Hotel was 90% occupied, so you had to reserve a chair under the umbrella (Beach or Pool) well before 8 AM. A lot of families with children, not in the Bar pool (pool small there). All in all would return again as the color of the water is truly a site not to miss. Did not even care to venture off the property as it was too beautiful to leave. Did see the ruins at Chichen Itza (full day trip).

We spent six nights at the JW Marriott in July. It is a lovely hotel.
We found the service to be excellent as well; we never had any problems. Our room was quiet, well air-conditioned and beautiful. All the rooms have balconies, whereas at the Ritz Carlton and Le Meridien you have to upgrade to get a balcony. We had a gorgeous view of the pools and the water. There is some construction on one of the pools on the north side, so request a room on the south side if you're going there in the next couple of months.

The bathrooms are especially pretty, and come with all the creature comforts: comfy robes, good quality soap and shampoo, separate shower, tub and toilet, etc. Everything is marble, wood, and granite. The maids come in the late morning, and turndown service is in the late afternoon to early evening.

The real standout is the spa. There is a large, beautiful indoor pool that overlooks the lagoon, and at sunset one evening we even had it to ourselves. The spa facilities are first rate. It's free to use the workout room and pools. If you want to use the saunas and steam rooms, it's an extra $10 a day. The pools outside are large enough that you're not on top of kids all the time, which we appreciated, and the infinity-edge pool is especially nice. Tip: Go down first thing in the morning and save your spot if you want an umbrella.

The restaurants were good, though not inexpensive. Be sure to get an E-plus card and the coupons that they give you at the airport because there are coupons for all the JW Marriott restaurants. The only time we didn't get a discount was for the breakfast buffet at Salsa. The buffet is huge, and excellent.

I highly recommend this hotel. We would definitely stay there again.

My husband and I visited Cancun for the first time and couldn't be happier with our experience. It took me forever to decide where to stay as I wanted someplace very nice and very romantic. The JW Marriott was a wondeful hotel --- the room was spectacular and the service was truly first class. We stayed in a Grand Oceanfront Master Suite which I would highly advise. The room was stunning and you could easily hear the ocean waves as you were lying in bed. The service was amazing --- honestly everyone we came in contact was friendly and extremely polite.

We plan to visit Cancun again in the future and would stay at the JW again without question.

My wife and I have been going to Mexico for ten years and usually make one or two trips annually. Previously we had always gone to Acapulco, Puerto Vallarta, Mazatlan, Ixtapa, or Los Cabos. We finally went to Cancun and stayed at the J W Marriott. What a grand place. It is the best hotel we have ever stayed at in Mexico and that includes the Acapulco Princess, and the Westin Regina in Los Cabos and Puerto Vallarta. Everything was first rate: excellent service; beautiful clean rooms; and their signature restaurant, the Gustino Italian Beachside Grill is absolutely wonderful. The name belies its upscale ambiance.
This is not a casual restaurant.. don't think "beachside grill." Next to Ristorante CasaNova in Acapulco this is definitely our favorite restaurant in all of Mexico. The J W is not cheap but we believe we got our money's worth. We will definitely go back.
