Best for: Families who want plenty to do but don’t want to navigate a mega-sized ship
Sails: Bermuda, the Caribbean, New England and Canada
At a Glance: Many Vision-class ships specialize in exotic itineraries, but Grandeur of the Seas, scheduled for a refurbishment in 2017, sticks to short jaunts along the east coast, Bermuda, and the Caribbean. And though it’s much smaller than Royal Caribbean’s largest ships, it still has plenty of fun activities to choose from (rock climbing, anyone?).
