The average daily price for Pacific cruises varies dramatically depending on several circumstances. The length of your cruise and the type of cruise line are the two biggest factors in determining the cost. The fares on luxury lines like Silversea may be three to four times the cost of cruises on Holland America Line, Princess, or Celebrity for an Australia/New Zealand cruise. Cruises in Tahiti, a dream destination that really delivers, command higher fares from all cruise lines, often double what you pay per cruise day in any other region.
