Quantum of the Seas: Sanitation Record & Health Report
ShipTea Verdict
Quantum of the Seas just posted a perfect 100 on its latest CDC inspection (March 10, 2026), climbing from a 98 the inspection before that. Two data points isn't a mountain of evidence, but "improving" and "flawless" are a nice combination to have on record, especially when the fleet-wide average latest score across the 162 ships we track sits at 96.7 and the median is 98. Quantum isn't just clearing the bar here, it's standing on top of it doing a victory lap. We don't have outbreak data pulled up for this one right now, so we're not going to pretend to know that history one way or the other — just know the sanitation scores themselves are about as clean as they get.
This is a 2014 build that got a proper refresh in 2024, so you're getting Quantum Class's greatest hits — the North Star capsule, the bumper cars, the skydiving simulator, all the gimmicks that made this class famous for treating a cruise ship like a floating amusement park — without the "why does this decade-old carpet smell like that" energy some unrefurbished ships carry. At 168,666 tons and carrying over 4,000 guests, it's a proper mega-ship, and its current schedule leans heavily into Brisbane (29 sailings) with a smaller Pacific Northwest presence out of Seattle (17) and just a handful from Los Angeles (3) — so depending on where you live, this might be your easiest mega-ship access point or a total non-option.
Who it's for: families and thrill-seekers who want the theme-park version of a cruise and can now point to a genuinely strong, trending-up health inspection record while they do it — especially anyone sailing out of Brisbane, since that's clearly this ship's real home base these days. Who should skip it: purists chasing an intimate, quiet-adults vibe, or anyone who wants a longer inspection paper trail before trusting a ship with their stomach — two inspections is a good start, not a decade of proof. For now, though, Quantum of the Seas is earning its Smooth Sailing rating the honest way.
