The first thing to consider about cruising is to figure out where one wants to go. This will help determine the type of cruise line to choose. Not all companies cover the same regions. For example, if you're interested in visiting Alaska to explore the shorelines and glaciers, you'll find that Celebrity Cruises, Crystal Cruises, Holland America Line, Norwegian Cruise Line, and Princess Cruises go there. If you're interested in the Caribbean Sea to do some island hopping, you'll find Carnival Cruise Lines, Celebrity Cruises, Disney Cruise Line, Holland America Line, Norwegian Cruise Line, Princess Cruises, and Royal Caribbean International going there. For Transatlantic Crossings, the Queen Mary 2 of Cunard Line will sail across the North Atlantic. A full list of who goes where is available on page 40 of the book.
