Samoa is also a fantastic place to visit in the South Pacific. I loved the beauty and tranquility of this destination. There are not a huge amount of resorts on their main islands so you do need to book early. We stayed at the Saletoga Sands and I can thoroughly recommend this resort. Fab swimming, snorkeling right off the beach and stunning sunsets every evening. I would also hire a car for a couple of days and get out to explore the island as there are some great things to see and do. Definitely an excellent family holiday destination.
