I booked the wrong room on my first cruise. It was my biggest regret of the 7-day voyage.

• 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.

My first night on a cruise ship was terrifying. The floor trembled beneath me. I was startled by booming noises coming from the decks above and below mine. Was that furniture falling, sliding, and crashing into walls? My imagination was riddled with anxiety.

I sat stiffly on the couch at midnight, determined to stay awake and prepared for disaster. I read the emergency instructions over and over for what felt like hours until I accidentally fell asleep.

I woke up to the sun shining through my cabin window. I rushed out the door to ensure everything was all right. As seemingly unfazed cruisers filled the buffet and lined up for the water slides, I realized I'd experienced a normal night at sea.

This was back in April 2022, when I booked my first cruise on Royal Caribbean's 18-deck megaship, 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 didn't realize I'd booked a room where the movement on the ship felt the strongest

After my first night aboard the ship, I wondered whether anyone else had a similar 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 prone to seasickness. Higher decks in the middle of the ship feel calmer and more stable, they said.

Since my room on the 18-deck ship was situated at the front of the eighth floor, I felt constant motion in my room. As someone who gets motion sickness from the slightest movement of bathwater, booking this room spoiled many aspects of my first voyage.

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 colliding.

During the days at sea, when the cruise ship didn't stop, I had an especially hard time eating and participating in activities. And I didn't feel rested for my excursions at port stops, which included hikes in the sun.

Some cabins can feel rockier than others, like those situated at the front of the cruise 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 a cabin's location can affect how much motion you feel while the ship is moving before booking my cruise. Next time, I'd choose a room closer to the center of the ship.
