The last of Royal Caribbean’s four Radiance-class ships, Jewel of the Seas debuted in 2004 and received a $30 million renovation in 2016, which added several new restaurants and a poolside movie screen, among other upgrades. This 2,191-guest vessel is a casually elegant mid-sized ship that straddles the big-ship, small-ship realm with her extensive amenities yet intimate feel. Still, it’s important to remember that Jewel of the Seas is a two-decade-old ship, its age is certainly showing, and another refurbishment would do wonders to keep it up-to-date.
