For us to go to Sydney Austrailia and sail New Zeland was a trip of a life time. We went 1/2 way around the world.
While Princess has no control over who sails with them there is a demographic of people who make the cruise uncomfortable. They push and shove and cut in line and just generally misbehave in relation to western standards of behavior. And it is not just Australia where you find them. We have had other trips on Princess where this same demographic behaved in a like manor. That trip was to the Mediterranean. Clearly there is no resolution for this just be aware that they are there and stand your ground.
The food on the Emerald was good and Princess has the best pizza kitchen of any cruise line. The dining rooms are well staffed but they fail to enforce their standard of dress. If they say it is a formal night then the minimum of dress should be business casual and not jeans and tee shirts. To establish a dress expectation and not enforce it is political correctness gone overboard. Cruise ships should just eliminate formal nights as dress expectation is not met and not enforced. If you have a standard enforce it. We did anytime dining which we prefer to a stated time.
Cabin appointed nicely and roomy. When the ship was redone they didn't insalate the walls with flexible materials. When the seas got rough the room squeeked and creeked very loudly as the walls were too ridiged. Very anoying at night trying to sleep.
