Carnival Cruise Line Responds to ‘Night Sweats’ with Blunt Advice
Some like it cold – but not that cold.
That’s the message Carnival Cruise Line Brand Ambassador John Heald had for a guest that complained about cabin temperatures aboard Carnival Jubilee, voted the Best New Ship when it debuted in 2023.
In a Facebook post on May 16, 2025, Heald responded to a passenger who said they had night sweats during their cruise because the thermostat wouldn’t drop below 69 degrees.
“We need the air conditioning cold,” the passenger wrote. “We were on the beautiful Carnival Jubilee, and it was not cold enough. We checked with the crew, and the cabin temperature was 69 degrees,” she wrote.
“We run our house between 60 and 65. Our cabin at 69 was far too hot,” she continued. “We are wanting to book the Jubilee again; we had a fabulous time. But we will not unless you can guarantee us it will be at the temperature that we want.”
Heald didn’t hold back.
“I like it cold, but 60 degrees is never going to happen,” he replied.
He also gave a candid warning, “I’m going to be honest. If you want it to be 60 degrees, don’t book. I don’t think you can book any ship where it will be 60 degrees.”
Heald used the video moment to warn upcoming passengers of warmer temperatures during the summer months and what to expect onboard.
“This is when the sea temperatures are at their highest,” he explained. “There will be times when public spaces are a little warm.”
He said many guests are caught off guard when boarding, especially on embarkation day.
“People sometimes panic on embarkation day. They walk on the ship and think, ‘It’s hot,’” Heald said.
Heald said that ships are more vulnerable to warmer indoor temperatures when docked and not yet underway because the ship isn’t in motion and many areas often closed to the elements are open, such as gangways and areas where the ship takes in luggage and supplies.
Vessels are oftentimes utilizing shore power, as well, which can have an effect of the capabilities of air conditioning.
“That’s why on embarkation day it might be a little hotter, but once those doors are closed and the ship is sailing, things will calm down,” Heald said.
Speak up on Board
The post led Heald to urge passengers who are uncomfortable while sailing with Carnival Cruise Line to speak to someone onboard rather than waiting until a cruise is over.
“Please don’t write to me afterwards and say it was too hot,” he pleaded. “Speak to someone, call guest services, tell your cabin attendant so the crew can do all they can to make it better for you during the cruise.”

Many longtime Carnival Cruise Line guests chimed in with support after Heald’s post, saying cabin temperatures had never been an issue on their sailings.
“After 14 cruises I can say we have never had a problem,” one passenger commented.
Others acknowledged that some areas of a ship can feel warmer during the day, despite setting the cabin thermostat as low as possible, which Heald said attendants automatically do for guests.
“60 is definitely way too cold, but I do feel at time it does get a little toasty,” one wrote. “I keep the curtains shut to help during the day. However, it would be nice to be able to get a fan.”
Unfortunately, Carnival Cruise Line, which may have a limited number of fans to dole out by request and more specifically for medical reasons, does not have enough fans to support all passengers.
Guests may pack fans smaller than 12 inches, as long as they are placed in carry-on luggage.
