We're taking Princess from SF to Sydney and Holland America from Sydney to LA. We've never been to this area and are looking for advice, especially on shore excursions. For instance, both lines have "Lord of the Rings" tours, but HA's is twice the time (8 hours) and twice the price. Do we really see a lot of the fantastic scenery from those movies on both tours or is one better? Any other shore excursion advice?
