Which cruise ship has the most pools?

Royal Caribbean's Icon of the Seas has 7 pools — more than any other cruise ship. These include the main pool, the Swim & Tonic swim-up bar pool, the Royal Bay Pool (the largest pool at sea at over 40,000 gallons), the Cloud 17 adults-only infinity pool, and several smaller pools in the Surfside family area. MSC World Europa has 6 pools including a rooftop infinity pool. Norwegian Prima has 5 pools including two infinity-edge pools. Most mainstream cruise ships have 2-4 pools.

Are cruise ship pools salt water or fresh water?

Most modern cruise ship pools use fresh water produced by the ship's onboard desalination systems. Some ships use a mix — the main pool may be fresh water while hot tubs use salt water. A few older ships and expedition vessels still use salt water pools. Royal Caribbean, Norwegian, Carnival, Celebrity, and MSC all use fresh water in their pools. The water is chlorinated and tested multiple times daily to meet health standards set by the CDC's Vessel Sanitation Program.

Can you use the pool when the ship is in port?

Yes. Pools, hot tubs, and water features remain open when the ship is docked in port. In fact, port days are the best time to use the pool because most passengers go ashore, leaving the pool deck nearly empty. The only exception is tender ports in rough weather, when the ship may temporarily close the pools for safety. Waterslides and water parks also remain operational in port on most cruise lines.

Do cruise ships close pools in rough weather?

Yes. When seas are rough, the captain may close the pools and drain them partially to prevent water from sloshing over the sides. Hot tubs are usually the last to close because their smaller size makes them more manageable in moderate seas. Indoor pools (found on Holland America, Princess, some MSC ships) and pools under retractable roofs remain open in almost all conditions. The decision is the captain's and is made based on wave height and ship movement.

Is there a lifeguard at cruise ship pools?

Policies vary by cruise line. Royal Caribbean has lifeguards at all pools and waterpark areas. Carnival posts lifeguards at pools during operating hours. Norwegian has lifeguards at family pools but not always at adult pools. Celebrity does not typically have lifeguards and posts 'Swim at Your Own Risk' signage. MSC has lifeguards at children's pool areas. Regardless of lifeguard presence, children under a certain age (typically 12-16 depending on the cruise line) must be accompanied by a parent or guardian at all pool areas.

Royal Caribbean's Icon of the Seas has the most impressive water features at sea — the Category 6 waterpark with 6 waterslides (including the tallest at sea), plus 7 pools and the Swim & Tonic swim-up bar.
