I'll start wi the not so great but despite the issues still a great stay.
I didnt get the room i booked for the whole time so needed to move and missed some of the culture day (definitely recommend the culture day!)
Was advertised as having WiFi in reception but you have to pay for it anywhere in the resort.(roaming expensive here for Aussies so buy local sim if you want to stay connected)
Was told i would get refund for early check in costs after flight delays but that was reneged which was a shame even after email comfirmation and comversation for refund on card(check your bill carefully and get cash rather than agree to credit refund)
Tour of south east cost was great but warning all single travelers per person actually means minimum of 2 so paid double.
If you're a waterfall lover just be prepared you cant swim in them all so not quite what i was wishing for.
There's very little sound proffing so dont expect a sleep in and hope for considerate neighbours.
If you choose the mini bar over breakfast make sure you get it on first day or you'll miss a days worth.
Locals were kind and helpful and Samoa is a great place to visit but be savvy.
