I took my first cruise on one of the largest ships of its kind. Booking the wrong room was my biggest regret.

• Booking a room at the front of the ship was my biggest regret on my first cruise.
• On Royal Caribbean's Wonder of the Seas, I learned that rooms at the front are bumpier than others.
• I booked the front room of deck eight and felt seasick for most of my voyage.

The first night of my first cruise was so bumpy that I stayed up all night preparing for an emergency — but everything was fine.

It was back in April 2022 when I booked a room on one of the largest cruise ships in the world, Royal Caribbean's 18-deck Wonder of the Seas. For $2,000, I spent seven nights in a 179-square-foot ocean-view stateroom at the very front of deck eight. It was a mid-tier room — a step above the windowless interior staterooms, a step below staterooms with a balcony, and two steps below a suite.

I unknowingly booked a room where movement on the ship felt the strongest

After my first rocky night aboard the ship, I wondered whether everyone had the same experience. So, I talked to some fellow passengers who were seasoned cruisers. They told me that the front of the ship is one of the worst places to be if you're often seasick. Higher decks in the middle of the ship feel calmer and more stable, they said.

Since it was at the very front of deck eight, I felt constant motion in my room. As someone who gets nauseous from a rocking chair in a living room, this spoiled many aspects of my trip. 

Some nights were rockier than others. On the roughest nights, I heard and felt a similar sensation to thunder beneath me every few minutes. Loud thumps and heavy vibrations in my room sounded like large pieces of furniture falling.

During the days at sea, it was especially challenging for me to eat and participate in activities. And I didn't feel rested for my excursions at port stops, which included hikes in the sun.

Some cruise ship cabins can be rockier than others, like those situated at the front of the ship

Cruise passengers prone to motion sickness should book a room in the middle of the ship to feel the least amount of rocking.

I wish I'd researched how the location of a cabin can affect the amount of motion you feel while the ship is moving before booking my cruise. Next time, I'd choose a room in the middle of the ship.
