When things get back to more normal then if you want to get to meet people who pretty much live as they have done for hundreds of years then Tonga is probably the most accessible place like that for you to try. Sunsail have a base there and you can get to some pretty basic but beautiful islands from that base.

I posted earlier in the game time threads some photos of Vanuatu which is even more representative of a country where you can step back in time. The charter infrastructure is very limited there so I think that is probably a step to far for a first charter away from the BVI.
