Princess cruises out of Brisbane is never at $100 a day, but I can see they are out of Sydney or Melbourne. I can understand why Sydney pricing is low as there are more visiting ships, but not Melbourne.
I can't compare cruise lines 12 months ahead because it's P&O or P&O out of Brisbane for 6 mths of the year. Even when Princess is here it's only over summer as they are off doing the world or Hawaii cruises.
Of the 3 lines we've cruised since cruising restarted, non of the are like the good old days.
