Royal Caribbean allows infants as young as 6 months old on most sailings, but requires infants to be at least 12 months old for transatlantic, transpacific, Hawaii, and any itinerary with 3+ consecutive sea days. Budget $150–$400 in extra baby-related costs per cruise beyond the adults' fare.

Most new parents eyeing a cruise are surprised by two things: Royal Caribbean's minimum age policy is stricter than it looks at first glance, and the baby gear logistics will cost you real money if you don't plan ahead. Here's the honest breakdown of what cruising with a 6-month-old on Royal Caribbean actually involves — rules, costs, and hard-won practical advice.
The Age Rules First — This Is Non-Negotiable
Royal Caribbean's verified policy: infants must be at least 6 months old as of the first day of the cruise. That's the minimum for standard Caribbean, Bahamas, Bermuda, and most short itineraries.
Dave's take: Royal Caribbean's crowd is genuinely more refined than you'll find on competing lines — less pool-deck chaos, more adults actually relaxing — which matters when you're trying to keep a baby on a manageable sleep schedule. The tradeoff is pricing that runs double or triple comparable Carnival itineraries, but on ships like Star of the Seas, that premium shows up in staff that seem to actually enjoy their jobs and a buffet that's a legitimate step above what you're used to.

Critical caveat: For any of the following, your baby must be at least 12 months old:
- Transatlantic crossings
- Transpacific crossings
- Hawaii itineraries
- Select South American sailings
- Any cruise with 3 or more consecutive sea days
That last point catches a lot of parents off guard. A 7-night Caribbean sailing that happens to have a 3-night sea day stretch disqualifies a 6-month-old. Check your specific itinerary's sea day count before booking — not after.
If the last name on your child's documentation differs from yours, Royal Caribbean requires the original or certified copy of the birth certificate plus valid documentation linking the names. Bring the birth certificate regardless — it's the fastest way to prove your child's age at embarkation.

What a 6-Month-Old Cruise Actually Costs
The baby fare on Royal Caribbean is typically heavily discounted or even $0 for the third/fourth guest in a cabin (varies by sailing and cabin category). But the real cost is everything else.
| Expense Category | Budget | Mid-Range | Splurge |
|---|---|---|---|
| Baby's cruise fare | $0–$50 (3rd guest deal) | $100–$200 | $200–$400 (own berth) |
| Diapers & wipes (7-night supply) | $30–$50 (pack your own) | $60–$90 (buy onboard if available) | N/A — just pack them |
| Baby food (7 nights) | $0 (purees from MDR) | $30–$60 (jars from home) | $80+ (specialty ordered) |
| Travel crib/pack-n-play rental | $0 (request via ship) | $0 | $50–$100 (shoreside rental if needed) |
| Laundry (onesies multiply fast) | $30–$50 (self-serve) | $60–$90 (valet bag) | $100+ (per-item service) |
| Shore excursion adjustments | $0–$50 (skip some) | $100–$200 (baby-friendly options) | $300+ (private tours) |
| Travel insurance (add infant) | $40–$80 | $80–$150 | $150–$300 |
| Realistic total extras | ~$100–$200 | ~$300–$500 | $600+ |
Important: Royal Caribbean does NOT stock diapers, wipes, or creams for guest use. This is verified policy. Pack everything you need for the entire sailing plus a 2-day buffer for delays. Don't gamble on finding Pampers in Nassau at 7am.

Key Factors That Drive Your Costs Up
Cabin size matters more than ever. A standard inside cabin with a pack-n-play leaves almost no floor space. Seriously consider a balcony or Junior Suite — the extra square footage isn't a luxury splurge with an infant, it's a sanity purchase. Balcony cabins also give you an outdoor space to settle a fussy baby without disturbing other guests at 2am.
Itinerary sea days are the deciding factor on eligibility — and also on your stress level. More port days = more stroller walks, beach time, and ways to entertain a 6-month-old. Sea-heavy itineraries mean more time managing a baby in a small cabin.
No kids' club for infants. Royal Caribbean's Adventure Ocean program starts at age 3, and children must be fully potty trained. Your 6-month-old does not qualify for any supervised childcare on the ship. You and your travel partner are the entire childcare team, 24/7, for the duration of the cruise. Factor that into your itinerary choice.
Drink packages and your spending. Both adults in the cabin must purchase the same beverage package if one does. If you're nursing or on limited alcohol, the Royal Refreshment Package at ~$35/day (typical pre-cruise rate, $29–$42 range) covers specialty coffees, juices, and mocktails. Check your Cruise Planner for your sailing's exact price — it's always cheaper pre-cruise than onboard.
Gratuities are $18.50/person/day for standard cabins. Your infant will likely be charged gratuities as a passenger — confirm with Royal Caribbean at booking. On a 7-night sailing that's $129.50 per adult in tips alone.
Practical Tips to Actually Survive This Cruise
Book a balcony cabin minimum. The extra $100–$300 total over an inside cabin is the single best money you'll spend. Outdoor space for nap time, white noise from the ocean, and somewhere to go when the baby is unsettled at midnight.
Request a pack-n-play before you sail. Contact Royal Caribbean's accessibility/special needs desk ahead of sailing. It's complimentary but supply is limited. Don't assume one will be waiting — confirm in writing.
Bring ALL baby consumables from home. Diapers, wipes, rash cream, formula, baby food pouches, medications — all of it. The ship does not stock these. Your port stops may not have reliable availability either.
Talk to the main dining room on day 1. The MDR kitchen can often puree foods from the menu for infants. Ask your head waiter on embarkation night what they can do — many parents are pleasantly surprised. This can eliminate the need for jarred food entirely.
Choose a short, port-heavy itinerary. A 5–7 night Bahamas or Caribbean sailing with 1–2 sea days is the sweet spot. Keeps the baby eligible (6-month minimum applies), gives you port distraction, and limits the consecutive sea day risk that bumps the minimum age to 12 months.
Buy travel insurance that explicitly covers the infant. Medical evacuation from a cruise ship with an infant is not a scenario you want to face uninsured. Budget $80–$150 for a solid family policy.
Pack a baby carrier/wrap. Strollers are awkward on gangways and tender boats. A carrier is how you navigate ports, pool decks, and the buffet line with a 6-month-old without losing your mind.
Skip the Refreshment Package for the nursing parent — if you're predominantly drinking water and the occasional coffee, paying $35/day doesn't pencil out. Buy specialty coffees individually (typically $6 each) and grab free buffet beverages.
Best Royal Caribbean Ships for Families with Infants
Not all ships are equal for a 6-month-old.
| Ship Class | Why It Works for Infants | Watch Out For |
|---|---|---|
| Wonder/Icon of the Seas class | Large, stable, tons of space to roam | Overwhelming crowd size; book early for quieter areas |
| Oasis/Allure/Harmony | Central Park is peaceful, great for stroller walks | Complex ship to navigate with baby gear |
| Freedom class | Manageable size, good pool deck, strong Caribbean routes | Fewer splash areas |
| Navigator/Mariner | Smaller, less crowded, easier to navigate | Fewer amenities |
| Explorer/Adventure | Good Caribbean itineraries, mid-size manageable | Older ships, cabin sizes vary |
For a first-time cruise with a 6-month-old, I'd lean toward Navigator of the Seas or Mariner of the Seas — short Bahamas/Caribbean sailings, not overwhelming in size, and the itineraries keep you under the 3-consecutive-sea-days threshold that would make your baby ineligible.
Before you book, run your full cost estimate — cabin, gratuities, drink packages, and all the baby extras — through CruiseMutiny to make sure the number you're budgeting actually matches what you'll spend on board. The last thing a sleep-deprived new parent needs is a $600 surprise on their SeaPass account at the end of the trip.
