Turns out those private hot tubs on cruise ship balconies might not be as relaxing as you think. Royal Caribbean just warned passengers about Legionnaires’ disease, a rare but serious illness linked to bacteria that can grow in less-used hot tubs. The CDC says these private tubs aren’t cleaned as often as the public ones, making them a sneaky hotspot for germs. If you’re cruising soon, maybe skip the solo soak and stick to the pool! #CruiseLife #TravelTips #RoyalCaribbean #Health
