We spent 7 nights at Le Lagon at the end of January just after the Cyclone. Luckily (at this time of year the weather is pot luck) we had good weather and a great time.
Most of the info about Vanuatu on this site we found spot on.
We took our five year old and she loved it. She loved kids club when we put her in and loved the pools.
We tossed up about taking the all inclusive package or the breakfast only package. Settled on the breakfast only package and were happy with the choice as it allowed us to eat wherever and try all different places. Breakfast was great and we ate dinner at the Asian restaurant at the resort twice, really enjoyed their teppanyaki. Prices are not cheap, similar to Aussie. Had a great Seafood platter at Erakor resort on the night we got there, set the tone for the whole holiday. Rendez Vous restaurant has the best view of the harbour and Irriki Resort. Food was good but waiter a little to in your face (tried too hard).
We had a waterfront deluxe (#109) which was down near the Erakor ferry end of the resort. It was worth every cent just for the view over Erakor Lake.When we got there they tried to put us in a garden room. I politely insisted on a 100 series room as we were told these were the best. Initially they said tomorrow night we swap you over, but i insisted and once a more senior person was called we had no problems.
I loved Vila but my partner didnt enjoy it as much. It is third world and lots of garbage in back streets but i like seeing how it is. Markets were excellent and even had a fish and rice meal at the back of the markets one day for about $A 4.
Worst exchange rate we got was 82 vatu to the dollar at Goodies. Leaving Australia at Travelex they offered 71. Biggest rip off. I bought Auusie dollars and changed it as i needed it. Could have taken money out at ANZ atm (Visa Debit) but did not know the rate.
Also grog definitely cheaper in Vila or even the airport over there. Duty free at Brisbane airport is the biggest rip off.
Found buses best form of transport. 100V per head into town. Met one guy and got his number and rang him whenever we needed him. Taxis are more prevalent but dearer unless there is a group of you.
Loved the Mele Waterfalls, got our bus driver to take us there and paid i think 1500V entrance fee, much cheaper than any tour. Also did Lelelpa island cruise which was excellent and our 5yo was free. Lunch was ok but nothing special, Snorkelling off the beach was disappointing compared to the Barrier reef but the second spot they take you to where you Snorkel from the boat was excellent. Tour guides were great and enjoyed meeting the villagers and buying some craft.
Probably should have checked out Santo and or Tanna, but in 7 days and with a five year old we took it a bit easy.
Always check your bill at the resort to see daily charges, we had no problem but have heard of plenty who have.
The resort itself is beautiful and plenty to do there if you want to.
Hope this helps.
