Re: Vava'u, Tonga
I spent a couple of cruising seasons there. Great sailing and diving. Affordable and laid back. You will need a good hurricane mooring in the extreme SE part of Niafu harbour.
Beluga Diving took my money for emails I tried to send from their computer, but didn't bother sending them.The library is better and more reliable. The internet situation is probably far better there by now.
