After our day/night in Tahiti, we hopped on the ferry to Moorea. If you're thinking about going to FP, the ferry is a great option - it's a beautiful 40 min trip and cost something like $15/each.
Our room wasn't available for the spontaneous extra night in Moorea, so we ended up in a little bungalow with a private pool. It was a beautiful option and a plunge in the colder water pool felt great after a massage.
We spent the morning of our second day renting a car and driving around the island. It's possible to drive the entire coastal perimeter of the island in 2 hours, or 4 hours with stops and lunch. We had wanted to explore a little bit, and it worked out perfectly because our actual room was ready for us when we got back to the hotel.
