Royal Caribbean Cruises 2025: Guide to Rules, Costs & Best Ships

Planning your first Royal Caribbean cruise brings plenty of excitement and a few head-scratching questions. Between the “washy washy” greetings, the mysterious wife-on-board jokes, and the ever-present 3-1-1 rule, it helps to have a clear guide. This piece walks through the practical details that matter most—what you pay, how you pack, and which ship fits your trip.

Royal Caribbean ships in fleet (2025): 28 ·
Annual passengers (approx.): 6.5 million ·
Cheapest month historically: January ·
Standard carry-on liquid limit (TSA 3-1-1): 3.4 oz (100ml) per container ·
Founded: 1968 ·
Headquarters: Miami, Florida, USA

Six key specs shape the Royal Caribbean experience. One pattern: the fleet spans from intimate ships for couples to mega-resorts carrying over 7,000 passengers.

What is the 3-1-1 rule on Royal Caribbean cruises?

The 3-1-1 rule is a TSA regulation that governs liquids in carry-on luggage. All containers must be 3.4 ounces or less and fit inside a single quart-size clear bag. — TSA official guidelines

The 3-1-1 rule is a TSA (US Transportation Security Administration) regulation that governs liquids in carry-on luggage. It applies to all passengers flying to a Royal Caribbean departure port, not just US citizens.

What counts as a liquid under TSA rules?

• Liquids, aerosols, gels, creams, and pastes all fall under the rule (TSA official guidelines)
• Each container must be 3.4 ounces (100 ml) or less
• All containers must fit inside a single quart-size clear zip-top bag
• One bag per passenger

Can I bring larger toiletries in checked luggage?

• Yes—checked bags allow full-size containers like sunscreen, shampoo, and mouthwash (TSA official guidelines)
• Royal Caribbean follows TSA guidelines for US departures
• For European departures, EU liquid restrictions (up to 100ml per container, single 1-liter bag) apply (European Commission aviation security)

The pattern: your departure airport dictates your liquid rules—Dublin means EU limits, US airports mean TSA limits. Check before you pack.

What is the cheapest month to go on a Royal Caribbean cruise?

January consistently offers the lowest fares for Caribbean cruises. The post-holiday lull combined with off-peak weather creates a sweet spot for budget-conscious travelers. — NerdWallet analysis

January consistently offers the lowest fares for Caribbean cruises. The post-holiday lull combined with off-peak weather creates a sweet spot for budget-conscious travelers.

Are there seasonal price differences for Caribbean cruises?

• January is typically the cheapest month due to post-holiday demand drop and favorable Caribbean weather (NerdWallet analysis)
• September and early November also offer lower prices but coincide with hurricane season (NerdWallet analysis)
• Summer and Christmas holidays command peak pricing—expect 30–50% more than January fares

How far in advance should I book to get the best deal?

• Booking 6–12 months ahead often secures lower fares (NerdWallet analysis)
• Last-minute deals (within 60 days) can be cheaper for unsold cabins, but selection is limited
• For Ireland bookings, deposits are €100 per person for 1–5 nights, €165 for 6–9 nights, and €165 for 10–14 nights (Royal Caribbean Ireland Booking Conditions)
• Suites require a non-refundable deposit of 10% of the cruise fare based on double occupancy

The trade-off: off-peak pricing saves money but carries weather risk. September and October cruises are cheaper—but a hurricane reroute is a real possibility. For European itineraries, shoulder seasons (April–May, September–October) offer the same pattern.

Which Royal Caribbean cruise ship is the best?

“Best” depends on who you’re traveling with. The fleet spans from the massive Icon of the Seas to smaller, quieter ships designed for adults.

What are the top ships for families?

• Icon of the Seas (2024) is the newest and largest, with six waterslides, a kid’s aqua park, and family-friendly neighborhoods (Wikipedia entry on Icon of the Seas)
• Oasis-class ships (Symphony, Wonder, Harmony) feature boardwalk areas, carousels, and Broadway-style shows (Wikipedia entry on Oasis-class cruise ship)
• Wonder of the Seas (2022) is the second-largest ship globally and has broad family appeal

Which ship is best for adults or couples?

• Smaller ships like Serenade of the Seas or Brilliance of the Seas offer quieter, more intimate experiences (Wikipedia entry on Royal Caribbean fleet)
• Radiance-class ships have panoramic views and relaxed atmospheres, ideal for adults
• For Mediterranean itineraries, smaller ships can access ports mega-ships cannot

The pattern: families with kids should book Icon or an Oasis-class ship for built-in entertainment. Adults wanting a quieter trip should pick a Radiance-class ship. No single ship serves both groups equally well.

What does washy washy mean on a cruise ship?

First-time passengers often notice the cheerful “Washy washy!” greeting near dining areas. It’s one of Royal Caribbean’s quirkiest traditions.

Who is the “Washy Washy” person?

• Crew members stationed at buffet and dining entrances sing “Washy washy” while offering hand sanitizer (Wikipedia entry on Royal Caribbean culture)
• It became a popular catchphrase on Royal Caribbean ships and is often memorably delivered
• The phrase reinforces the line’s hygiene protocols in a lighthearted way

Is hand sanitizer mandatory on Royal Caribbean?

• Hand hygiene stations are provided and encouraged at dining venues
• While not strictly mandatory, crew members actively remind passengers to sanitize
• During norovirus outbreaks, sanitization becomes mandatory and monitored

The catch: “Washy washy” is playful marketing for a serious hygiene protocol. Norovirus spreads quickly on cruise ships, and hand sanitizer reduces risk significantly. The song makes compliance feel friendly—not clinical.

What are five foods to avoid on a cruise?

Buffet dining is convenient, but some items carry risks. These tips apply to Royal Caribbean and cruise ships generally.

Which buffet items are best to skip?

• Raw or undercooked seafood (oysters, ceviche) unless served fresh and immediately (CDC Vessel Sanitation Program)
• Food left at room temperature for extended periods—avoid items that look dried or crusted
• Unpeeled fresh fruit in regions with questionable sanitation practices
• Dishes with runny eggs (Hollandaise sauce) if temperature-holding isn’t visible
• Buffet items that have been sitting out during peak sun hours on outdoor decks

Are there any safety concerns with cruise food?

• Stick to freshly cooked items and reputable dining venues on board
• Royal Caribbean’s main dining room uses stricter temperature control than buffet stations
• Hand washing before meals is the best prevention

The implication: stick to main dining rooms for hot meals and treat the buffet as a backup, not a primary option.

What does “wife on board” mean on a cruise ship?

This phrase pops up in cruise forums and social media, but it’s not an official Royal Caribbean term.

Is “wife on board” an official term?

• No—it is not an official Royal Caribbean term or policy
• The phrase is a humorous or informal nickname used among passengers
• Some cruisers use it to describe traveling with their spouse, playing on “wife” vs. “girlfriend” dynamics

What does the phrase refer to in cruise culture?

• In cruise forums, it often appears as a joke about spousal dynamics on board
• It has no connection to any safety protocol, reservation status, or passenger category
• Treat it as cruise community slang—harmless but not official

What this means: if you hear “wife on board” from a crew member, it’s likely a joke, not a policy. No need to take action or worry.
