Royal Caribbean Wonder of the Seas

The world’s largest cruise ship (until it’s beaten by its own sibling-to-be in early 2024), Wonder of the Seas is a massive — and massively compelling — option for mega-cruise fans. It has so many onboard experiences, from ziplining and surf simulators to karaoke and 21 different dining venues, that you’ll be hard-pressed to do them all on a weeklong sailing. That makes it terrific for active families and couples who like to stay busy trying different things. Just be warned: There could be as many as 7,000 other passengers wanting to try them too.
