We spent a week at W Maldives as a couple in Dec 2013. The Ocean Villa was a wonderful experience, with the ability to snorkel off the reef. Ku Nakanelua, the W Insider, made a real difference in the trip with her personalised service and knowledge. Ku also sent us a hello email months after we left the resort. Thanks to Ku, we still enjoy living next to the W Hotel in Singapore. There was some issues with service from the front desk, but Ku sorted it out. Service recovery does matter.
It's a small island, you can walk around it in less than 10 mins. If you like being alone as a couple, water sports, and just chillling out than this is the place for you. If you need lots of activity and people, more than 3 restaurants, than you may have to find a larger island or a much larger resort. Overall, we enjoyed the trip and would come back again.
