What to Pack in Your Cruise Carry-On Bag

When you’re getting ready for a cruise, it’s easy to focus on your main luggage—what outfits to bring, what theme night accessories to pack, and making sure you don’t forget the sunscreen. But one thing that often gets overlooked? Your cruise carry-on bag.

Your carry-on is a must have for embarkation day. Since your checked luggage can take several hours to arrive at your stateroom, you’ll want to be sure you’ve got all the essentials with you, from medications and valuables to swimsuits, snacks, and anything your kids might need right away.

Even after going on plenty of cruises, I still get that little pre-cruise excitement (and stress!) when it’s time to pack. Having a detailed cruise packing list always helps me stay organized and that includes a separate checklist for my carry-on.

In this post, I’ll walk you through exactly what to pack in your cruise carry-on bag, along with some of my favorite recommendations for carry-on luggage and must-have travel items.

Why You Need a Carry-On Bag for a Cruise

Your carry-on bag will hold everything you need for the first few hours on the ship: swimwear, important documents, medications, valuables, and anything else you don’t want packed away in checked luggage. Think of it as your cruise day survival kit!

You’ll want to start enjoying your vacation right away, maybe hit the buffet, relax poolside, or explore the ship and so being prepared makes all the difference.

What Kind of Carry-On Bag Should You Bring?

This all comes down to personal preference! Here are a few great options:

• Large Tote or Beach Bag: Perfect for doubling as your shore excursion bag later in the trip. Look for one with a wide strap and extra pockets.
• Backpack: My son swears by this, it’s comfortable, compact, and fits everything he needs.
• Small Carry-On Suitcase with Spinner Wheels: Ideal if you want to roll rather than carry. Great for families or those packing extra items.

Top Carry-On Bag Recommendations

1. Hardshell Carry-On Luggage
   Durable, easy to roll, and fits under airplane seats or in overhead bins. Great for short cruises or packing light.
2. Expandable Travel Backpack (40L)
   This powerhouse backpack fits like a suitcase and includes packing cubes. A lifesaver for cruisers who like to stay mobile.
3. Packing Cubes
   Keep your carry-on neat and organized. I personally love compression packing cubes for saving space.

Embarkation Day Cruise Carry-On Tips

Embarkation day is finally here—woohoo! But before you step onto the ship and start your dream cruise, there’s one super important thing to prepare: your cruise carry-on bag.

When you arrive at the cruise terminal, you’ll hand your luggage to the porters, who will safely deliver it to your cabin. However, it can take several hours before you see your bags again. That’s why having a well packed carry-on is key to a smooth and stress-free first day onboard.

Here’s what you need to know to pack smart for embarkation day:

✅ Must-Have Essentials

1. Passport & Government ID
   Keep it in a secure, easy-to-access spot. A passport holder that goes around your neck or waist is ideal. Do NOT pack it in your checked luggage!
2. Cruise Documents
   Have your boarding pass, luggage tags, and any shore excursion confirmations printed or stored in a travel binder.
3. Medications
   Pack all prescription meds, plus a mini first-aid kit with pain relievers, antacids, and allergy meds.
4. Motion Sickness Relief
   Bring what works for you: Bonine, Dramamine, SeaBands, ginger candies, or motion sickness patches.
5. Toiletries
   Toothbrush, toothpaste, deodorant, hairbrush, hand sanitizer, and any must haves you’ll want before your suitcase arrives.

👓 Valuables & Personal Items

6. Jewelry or Watch
   Bring only what you’ll wear and store in your stateroom safe once onboard.
7. Electronics
   Keep laptops, tablets, cameras, chargers, and any fragile tech gear in your carry-on.
8. Portable Charger
   Super handy on the go, especially if your cabin doesn’t have many outlets.
9. Reading Material
   Bring a book, Kindle, or magazine to enjoy during downtime.
10. Sunglasses & Reading Glasses
    Don’t forget backups if you wear reading glasses occasionally!
