ShipTea Verdict

Wonder of the Seas rolls into the CDC report card with a 95 on its latest inspection — passing with room to spare, since anything above 86 clears the bar, but notably below its own personal best of a perfect 100 back in January. The all-time average sits at a very respectable 98, matching the 5-year average, which puts this Oasis-class behemoth solidly above the fleet-wide median of 98 and comfortably north of the 96.7 average we track across all 162 ships. Four inspections in its short life (2025-09-05 through 2026-05-11) tell a story of a ship that started strong, peaked at 100, dipped to 99, and then slid to 95 — officially a declining trend, even if "declining" here just means "elite" going to "very good." On the food safety side, it's a flex: a spotless 100.0 score and the "Spotless Galley" grade, so whatever's happening in those 18 decks' worth of kitchens, someone is running a tight ship, pun very much intended.

Let's be real about scale for a second: this is a 236,857-ton, 5,734-passenger floating city with 2,300 crew members trying to keep every single surface sanitized across nearly 20 decks, and it's still clearing inspections at a rate most restaurants down the street would envy. For context, Royal Caribbean's mega-ships don't get an easy pass just because they're enormous — bigger footprint usually means more opportunities to get dinged — so a 95 with a 98 all-time average is Wonder of the Seas essentially shrugging off its own size. We don't have current outbreak data available for this one (CDC's outbreak database is being cranky right now), so we're not going to pretend it's spotless on that front — we simply don't know, and neither should you assume it either way.

Who it's for: anyone who wants the biggest, splashiest Royal Caribbean experience without losing sleep over sanitation — families, first-time mega-ship cruisers, and anyone who treats "Spotless Galley" as a genuine selling point deserve to feel good about this one. Who should skip it: the sanitation-obsessed who need to see three consecutive 100s before they'll relax, since the recent dip to 95 (even though it's still a comfortable pass) might needle anyone allergic to any downward arrow on a chart. Everyone else, book with confidence and let the buffet anxiety go.
