If you’re going to travel that far, why not do it in a big way? That could be Holland America’s 93-night Grand Australia & New Zealand Voyage (Jan. 3 to April 6, 2024), roundtrip from San Diego on 1,432-guest Volendam. The itinerary calls on 19 islands throughout the South Pacific and visits 17 ports in Australia (including Sydney, Melbourne, Brisbane, and Adelaide) and seven ports in New Zealand.
