Getting There -- We flew on Air Tahiti (as part of the package with Princess) from L.A. The flight is about 8 hrs. and the Airbus 340 is very comfortable and the service is good. Avoid the charter that Princess uses, Omni. We heard more horror stories from people that had flown on Omni. We stayed over a few extra days at the end of the cruise so that prevents you from flying on the charter.
The Ship -- We have cruised several times and this is the smallest ship we have been on. It holds about 650 passengers, which I think is a nice size. We rented a mini-suite which is well worth the extra money. The cabin is about twice the size of normal cabins and the balcony is also about twice the size of other balconies.
The pool is tiny and they should get rid of the hot tubs and expand the pool a bit. Hot tubs in this climate seem crazy, but they were used a lot.
