Carnival Cruise Line shares warning about concerning cabin ‘hack’
No matter how hot and bothered you are, be careful about taking cruise advice from online forums.

Many cruisers turn to online forums like Reddit, Facebook groups, and cruise website message boards for tips and advice about cruises.
These forums can be a wealth of cruise information, but it’s important to keep in mind that not all of the tips and “cruise hacks” you find on them — even popular ones — are wise.

Some cruise hacks violate cruise line conduct policies and could get you banned from sailing. Some can also jeopardize your safety and the safety of others.
Although some cruise hacks are smart and helpful, you probably shouldn’t try any that sound questionable. If you’re unsure, consult your cruise line’s guest conduct policies or contact its guest services team.
Cruise lines want to make it easy for passengers to understand what onboard behaviors are discouraged. Guest conduct policies are quite detailed to help prevent any doubt, and to help ensure a safe and enjoyable onboard experience for all.
For Carnival Cruise Line passengers, there’s even an easy way to reach out directly on social media to a helpful cruise line representative.
Carnival Cruise Line Brand Ambassador John Heald manages a popular Facebook page where he answers hundreds of questions from passengers every day. Heald also posts helpful information that cruisers need to know, including warnings about rumors and cruise hacks that passengers should ignore.

New Carnival cabin air conditioning hack poses safety risk
In a video message posted on June 14, Heald shared a serious warning for Carnival cruise passengers after a concerning cruise hack was brought to his attention by both cruisers and a staff member who monitors social media sites for the cruise line.
This Carnival cruise cabin hack was posted on a cruise message board and suggested a questionable way to make the cabin air conditioning get cooler.
“Basically, what they're saying is you can go into the thermostat, take the thing off, switch some wires around and bypass and sort of try and make it cooler yourself, I guess,” Heald explained.

Heald said he didn’t really know what this air conditioning hack was telling people to do exactly, but what he did know was that passengers should not attempt it because it’s extremely unsafe.
“I spoke with one of the engineers about this on one of the ships, and not only is that something that is very likely to give you an electric shock and really injure you, but also it's very dangerous as well from a fire safety point of view,” Heald explained.
What to know about cruise ship air conditioning
As he warned passengers against this cruise air conditioning hack, the brand ambassador also encouraged Carnival cruisers not to hesitate to reach out to guest services if they have a problem with their cabin air conditioning.
“Please don't write to me at the end of cruise when you're back home in Cleveland and say it wasn't cold enough in my cabin,” Heald stressed. “Talk to somebody on board there — call 7777, go to guest services, tell your cabin attendant, do whatever is necessary.”
Heald also explained why it may feel like cruise ship air conditioning systems aren’t cooling as well as they should, especially during the hot summer season.
“The ship uses a cooling system — a cool water system — which takes the cold water from the engines and the engine room and pushes that through into the air conditioning. Now, remember this time of year the water temperatures in the Caribbean...can be very warm and so just bear that in mind — it is the very warm and humid time of year,” Heald said.

“But if you have any concerns in your cabin, please speak to somebody. Do not, do not tamper with the air conditioning system, please,” he reiterated.
The brand ambassador also warned that tampering with your cabin air conditioning system could get you banned from sailing on Carnival cruise ships.
“Not only is that very dangerous but it's a very good chance that you would stop yourself [from] ever being able to cruise with us ever again,” he added.
