Staying Connected: This is the line for you if you want to Instagram, Snapchat, Skype, and even stream movies while on board. Royal Caribbean has the fastest internet at sea, with high-speed Wi-Fi available fleet wide. For passengers who hate the idea of unplugging, this Voom internet service is a big bonus to cruising on Royal Caribbean.
Fast Boarding: The new check-yourself-in-at-home process, which allows you to go from the curb to your cabin in mere minutes, really sets this line apart. Best of all, you can upload a photo at home rather than having to take one (travel weary, bedraggled, and possibly even jet lagged) on the day you board.
Amusement Park-Style Activities: Some of these ships have bumper cars, a merry-go-round, miniature golf courses, ice skating rinks, and zip lines, and Harmony of the Seas also has the Abyss, which — at 10 stories tall — is the longest slide at sea.
Innovative Entertainment: The lineup includes full-scale productions of Broadway shows such as “Cats,” "Grease," and “Shrek the Musical.” In addition, animated DreamWorks characters make appearances in parades and shows on ice or in water. You can also see live aerialists interact with robotically controlled video screens.
Art Collections: Newer ships have impressive modern art collections, with interactive installations that move and change, and playful, colorful static pieces throughout.
