OK, first I have to disclaim that it's been 20 years. But I did a week of my honeymoon in Tahiti. The best advice I got was to get off the main island of Tahiti - you will fly into Papeete, the main town there. We spent 3-4 days in Morea which was only a short boat ride. The boat ride itself was nice. We really enjoyed Morea. At least back then it was not that populated - not nearly as much as the main island. Then, we flew to Bora Bora which was even smaller than Morea. Both were nice, it was fun to have the change-up in islands. But honestly, they weren't that much different as far as beauty & activities. So, you might consider Morea which would skip the island-jumper plane flight.
It is beautiful, you'll love it.
We did Fiji on the same trip. I'd go back there before Tahiti, just in case you want to look into an alternative.
