My beloved has long yearned to do this, and would love to treat himself this summer, as a reward for graduting school.
He's seen a tour with Sea For Yourself snorkelling safaris in September. The accommodation would be at the Tongan Beach Resort 30 minutes drive from the town of Neiafu. The watching would be from Vava'u.
He's a very keen snorkeller and deserves a treat having studied very hard. But, this trip will cost an awful lot of money, probably around 5,000 GBP so I only want to book it if it's worthwhile. He'd being coming from the UK so a very long way to go, if it's a bit of a letdown.
Any tips/thoughts/help very gratefully received.
