2. Explorer of the Seas
The Explorer of the Seas lives up to her name. This is not just a cruise ship for passengers to explore though. The ship has a built-in laboratory that sends oceanic and atmospheric data to the University of Miami. She sails routes around Alaska and the islands of the South Pacific. Windows and balconies from cabins and suites make the most of the views. While you’re on board you can wave-surf on deck, go ice-skating and rock-climbing.
