Well, it's a matter of opinion which is a better location. Both in fact are good, you couldn't go wrong with either. Nuie is closer to the pools and GCH. Since you want first floor, Nuie would be fine. It is kind of boxed in between Rarotonga and the GCH in my opinion. I prefer Fiji just for the view. It has a good view of the marina or lagoon looking toward luau cove and GF. It's on the same side of the GCH as Captain Cook's and you just need to walk around the marina, a short distance, to get to the volcano pool. But then again I always want a balcony so that's another reason I would probably lean toward Fiji.
