One of the largest mainstream cruise lines in the world is Royal Caribbean, and they are known for their ships that are packed full of WOW factors and onboard thrills, from surfing and skydiving simulators to ice skating rinks, zip lines, rock walls, waterslides, and jaw-dropping Broadway-style musicals.
Despite the cruise line's name, their fleet of 26 ships sail all over the world. You can take an exotic cruise to the Southern Caribbean, spend an action-packed week in Alaska, or take in all the culturally significant sights in Europe. If you'd rather enjoy everything their ships have to offer, consider a longer transatlantic or transpacific voyage that has multiple days at sea.
