Cruisers must consider two basic factors while booking a world cruise – time and money. World cruises generally last for 90-120 days. Cruisers can even choose from different kinds of cruise ships with customized itineraries. If you are strapped for time and money, book a segment cruise which covers a region and lasts for 2 weeks or a month or more.
Grand voyages are lavish and huge. They are usually focused on a single hemisphere and cover a time span of 70 nights. Boomerangs transfer cruisers from one ship to another at the same port to change the course. Styles of the cruise ships vary as per you choose. When you look for itineraries consider the sea days, ports of call and onboard perks.
