I wasn't overly impressed with Oyster Island at all. The place was DEAD!! We were the only couple there, every night we ate alone, drank alone, there was no ambience!!
If you want to stay here, make sure you are prepared to pay for all your water, as the water isn't "safe to drink" which is a lie, as we know people who've stayed here numerous times over the years and the water has always been fine until recently.. sounds like another way to make money off the customers.
We asked them to fill our personal water bottles (with lime juice at the bottom) with the rain water they have there, and the owner was very quick to inform us that we will get sick from the rain water and they haven't washed the tank is over 5 years.. he said "look at the water it's got bits in it, I hope you're going to boil that" - it's lime pulp mate..!
We were expecting a hot water jug in our room as every hotel/resort we have stayed at before hand has had one for hot drinks. There wasn't one and when we inquired about it, he swiftly informed us that we could buy drinks at the bar. (How could we boil the "dirty rain water"????)
The wet dirty towels weren't changed over our stay, just hung outside to dry on the balcony. Nice surprise to come back to :)
If you're into snorkelling, this isn't the place to be, it's cloudy, and the visibility is below average! They tell you the waterhole close by is amazing, LIES! It's not blue. It's grey. They have put concrete all around it for the tourists and it have changed the water hole. It's not clear at all, I had to ask the man "is this the blue water hole?" When I arrived because it was nothing special. 500vatu... the kayak was nice though.
Despite all this, the local workers, the Nevans, were lovely. And Vanuatu is a beautiful country with so much to offer, just wouldn't recommend coming to Oyster Island :) the new management seems to be CHEAP and you can really see it.
