Do Accept that landowners will want payment (from around 500VT to 2000VT) if you use their land, for instance to visit a blue hole, a snorkelling spot or a beach.
Do Check with locals to find out if the local nakamal (meeting house and kava bar) is female-friendly. It’s rude to walk through a nakamal and they can be quite difficult to spot in rural villages when they’re outdoors and there’s no lighting.
Don't Bargain: prices are fixed, even at markets. Tipping is not expected either.
