Stay recommendation for January

We are visiting Rarotonga in January. I know it is the rainy season, and I have heard the Muri beach area, where a lot of the top accommodations are, is exposed to wind and rough weather at that time of year. Which area has more luxury accomodations but is more protected in case of storms?

We also play to visit Aitutaki for 3 days.. does Aitutaki get a lot of rain this time of year? We are used to passing showers but hope that there would be some good weather too.
