Royal Caribbean's cruises have never been this popular. Good luck booking one of its giant ships.

• Royal Caribbean Group has half the number of available cabins right now than the same time in 2023.
• The cruise giant has seen a string of record-breaking reservation weeks over the past three months.
• A trade group estimates 36 million people will go on cruises in 2024, a 14% increase from 2023.

Good luck booking your dream Royal Caribbean vacation this year — the cruise line's giant ships are running low on cabins amid a spike in demand.
