P&O Cruises created a new rule, but people disagree about it. P&O is a British cruise line for family and adult cruises.

The company sails to the Caribbean and Mediterranean. It made a new rule for sun loungers on sunnier cruises.

A customer shared a picture of a lounger with a fabric cover and writing.

The text said: 'Loungers get lonely. Don't reserve. If left for more than 30 minutes, belongings will be moved.'

The poster asked if the move was overdue or too much.

People often reserve sun loungers at dawn by leaving a towel.

This habit moved to cruise ships, and the rule change is divisive.

One person said a group of women did this on a cruise, and it was funny when their stuff was removed.

Another person said the rule was long overdue, and they often can't find a lounger.

A third person said the rule was enforced on a ship, and staff put stickers on loungers.

Someone said it's a great idea, and people should not leave empty loungers between them.

Some people don't think the 30-minute rule is fair.

One person said 30 minutes is too short, and an hour would be better.

Another person said an hour would be better for people to grab lunch.

A third person said 30 minutes is too short if you're just getting lunch.
