I prefer Regent Seven Seas Cruises (website: www.rssc.com
) to see the world; however, many cruiselines go to exotic ports. You can either look at cruiseline review section on CruiseMates which has links to the cruiselines websites or do a google search.
In addition to all the luxury lines, others that have exotic ports include:
There is a lot more of the world to see from a cruiseship than the Caribbean, Mexico, Alaska, or the Med.
Have fun researching!
