My fiancée and I are coming to the Cook Islands from September 2-7. We are looking to go somewhere beautiful and romantic. Should we go to Rarotonga or Aitutaki Island? Can you please recommend a very nice, on the beach (if possible) place to stay? It can be a resort, villa, house or bungalow. We are looking to pay between $150 to 250 per night, depending of how nice the place is.
