We've stayed at a number of other hotel resorts in Fiji and they are fairly similar, with just a slight variation in nuances. Not too much stood out for us at Sofitel, but it was a pleasant stay. The kids enjoyed the wee water slide (I haven't seen any other hotel pools with one) and the pool layout made for enjoyable swimming. As with most other resorts, a lot of selfish people put towels on the pool deck chairs early in the morning (and don't use the chairs most of the day), so it can be hard to find an available deck chair by the pool.
The beach was good and when we were there we noticed that it was less windy this end of Denarau than the Raddison / Wyndham end. Bring your own movies because the TV resolution for the inhouse system is abysmal. It was good that they offer free Internet, albeit you need to pay to get decent speeds.
Overall... friendly staff, good facilities, nice layout... a solid choice!
