Honeymoon in French Polynesia?

Hi everyone, my fiance and I are planning our honeymoon in the French Polynesia in May. We plan on going to Bora Bora for 5 days but keep hearing about Moorea and some of the other islands. We would like to go to the other islands but are ok not going on this trip since we want a more romantic and relaxing honeymoon but with things to do still. For a first time visitor, is it worth traveling between islands on such a short trip? How much were excursions compared to BB? Also, for those who didn’t book their hotel with a dinner package, how much did dinner cost you?

Thank you in advance for all of the information and suggestions!
