A day trip to beachcomber island is a must. The fish feeding is unbelievable, they will take food from your hands. Vanuatu's a laid back place. The people are friendly and the snorkeling and diving are great. There's plenty to see and do, including trips to an active volcano and many other highlights.
Prices are too high.
It's not Fiji, but they had a good time anyway. Go to the Travel Experiences page to find out about the Le Legon resort in Vanuatu. A great pool and some beach fun. Canoeing and building sandcastle. A friendly local and the resort from a catamaran.
