My family stayed at the Westing Lagunamar from Friday April 10 to Friday April 17. This was our first time in Mexico/Cancun. We really had been looking forward to this trip as Lagunamar had run into a delay and we had to postpone our original stay planned for June 2008. We couldn't have been more pleased and satisfied. The acommodations were grand. The view spectacular. The staff highly professional and reliable. If you want a beautiful rest and wonderful food and want to go to Cancun, this is the place.

Just came back from Lagunamar - this resort is really new and still under construction which is not annoying. I will try to sort good vs bad points:

Good:
Location - if you like shopping
Service - very good - hotel staff is really trying to make your stay pleasurable
Pool - if you came to Mexico for that
Value - we stayed for 4 nights for 200 USD and were given 100 USD voucher towards our stay.
Breakfast buffet is pretty nice

Bad:
Hotel is really new and there is almost no vegetation vs a lot of concrete
Location and hotel building complex - the location + the way hotel is built creates a Wind Tunnel effect - there will be constant wind blowing plus the waves will never calm down - the red flags on the beach are permanent fixture. If you came to Mexico for the pool experience - then it's no issue, however the pool area is very open and this plus the constant wind will make you shiver.
Mall food across the street - the restaurants are just food court quality for 4 star pricing - the Thai lounge is a good example.

We just returned from Cancun and the Westin Lagunamar Resort. The hotel is still under construction in some sections, but that was never an issue. We never heard a thing. Unfortunately the swine flu outbreak occurred just as we were arriving so we ended up spending more time at the resort than we had originally planned.
The rooms are amazing - all studios, 1 & 2 bedrooms. We had a studio and it was very well appointed, Westin's heavenly bed, flat panel TV, Bose Wave Music System, small but very functional equipment, great bathroom, whirlpool tub and separate stand-up shower. All rooms have a sea-view and walk out patio. We ended up making breakfast in the room most mornings and ended up sitting on the patio enjoying the start of the day, which was really nice.
On the resort grounds, the pool is the centerpiece. The infinity pool runs right up to the beach so you have a great view of the sea as you swim in the pool. As the resort is new the landscaping around the grounds is still a bit young and small.
My only complaint with the resort was the food. It was average for the most part though I did enjoy the ceviche at the lunch joint. Drinks weren't very good either though no complaints about the margaritas. The service was always good. All staff were very helpful and friendly. Housekeeping did a great job in the room daily.
Overall a very enjoyable stay and i would return to this resort.

We did a timeshare exchange and stayed at the Westin Lagunamar in February 2009. It is an absolutely beautiful resort. The pools and grounds are amazing. Our view was directly in front of the pools and the ocean and we could hear the ocean at night. The staff was very accommodating and friendly. They offered a timeshare presentation but merely made the offer and never mentioned it again when we declined. I don't think there is a better location in the hotel zone. It's directly across the street from La Isla Mall and the bus stop and we never waited longer than a minute or two for a bus. The decor is very attractive and the beds and bedding are very comfortable. The shower was amazing too. I've read other reviews taking issue with the cleanliness of the rooms but we didn't have any issues. Our room was clean and had clean linens and towels. The only thing that we weren't completely thrilled with was the food. It wasn't bad; just nothing special. In fairness we only ate there twice and never had a real meal but what we had was just average. We arrived late our first night and had appetizers by the pool and the buffet breakfast the following morning and ventured out for the rest of our meals during our week stay. The only time we had less that excellent service was at the buffet also. They had an omelet bar and the chef there ignored us refusing to look up at us when we tried to get his attention. When we mentioned this to the servers their excuse was that he didn't speak english. This excuse didn't float unless he was vision and hearing impaired as well. I don't go on vacation to do battle or beg for service so we gave up and grabbed cold cuts from the buffet and never went back. There are definitely better dining options and better prices up and down the hotel zone. We enjoyed La Destileria, Lorenzillo's, Casa Maguey and Captain's Cove. We went to Chichen Itza and Xel Ha during our stay and loved them both. The tour guide that we had at Chichen Itza was very informative and interesting. If you're shopping for souvenirs we found the best prices there also. I highly recommend taking the ferry over to Isla Mujeres and renting a golf cart to tour the Island. The atmosphere on the island is very kick back and it was a really relaxing day. We found a little sidewalk restaurant that had two for one drinks and there were lots of locals and tourists sitting under big umbrellas enjoying the day. We had a blast but I can't remember the name of the place. We're thinking of going back soon and I will stay at the Lagunamar again. We used US dollars during our stay but on the day that we went to Isla Mujeres the hotel concierge recommended that we use pesos because not all businesses there make change for US currency. Once we had the pesos I wished we had used them the entire trip it was much easier than trying to do the conversion and was fun to use. I loved Cancun and can't wait to go back.
