I had my honeymoon at the Cook Islands, about 6 years ago now, we also stayed at the Pacific Resort.

I too would second hiring a scooter, we both got our licence but only hired one scooter just took turns dinking each other. I know at the restort we stayed at they had an islander night which was themed had dancing etc.

We also took an inland tour in a 4wd, was quite interesting seeing the produce etc.

From memory there was a a market I think it was on the Saturday morning, unfortunately it was raining quite heavily so I didn't take much in as to what was their.

Hope you have a fantastic time, it is a beautiful place with lovely people.
