In my opinion you don't need to worry about the bungalow choice
at Le Moana. They are all good, I'd choose the one facing the lagoon,
not the one facing Mt Otemanu, as the view is obstracted anyway
(nothing like the view from Thalasso, more like a little mountain
behind a hill). You can have a view of Sofitel Resort island and it's great,
you will have an amazing sunrise every morning, or just the view of
"plain lagoon" and it's great too.
They are really good with upgrades, so you might even just walk around
and choose what you like.
Stephanie is a person to ask for, she is great and will help you.
