It is old, been abandoned for 4 years, so many things don't work anymore. The best example is hot water : there is none anymore... The food is generally terrible, except breakfast, and many people go to eat at a restaurant near by along the ocean. The staff is friendly, but average.
Anynway, for that price in a such place, the stay is quiet good.
Tuvununu is dead, and you are redirected to Maravu Plantation. This is an old 4 stars resort, which have been abandoned for 4 years, without maintenance. So now, staying at Maravu is a wonderfull environement, large natural park, large bures, at affordable price. If you go to Bouma park, you can see the old Tuvununu place, and you are happy to stay at Maravu ! A good point is that it is very close to the airport.
