How much does it cost to cruise on Symphony of the Seas?
Average cost per person for a 7-night cruise
- Cruise Critic reports average prices range from $700 to $1,500 per person for a 7-night interior cabin (Cruise Critic).
- Prices vary significantly by sailing date and stateroom category. A balcony or suite can push the total to $2,000+ per person (Royal Caribbean Official).
Factors affecting price: season, stateroom type, itinerary
Summer and holiday sailings command a premium. Off-peak weeks in the Caribbean (September–November) often offer the best deals. Planning a pre-cruise trip? Consider Car Rental Malaga Airport if your itinerary includes a European port.
All-inclusive packages and hidden fees
Gratuities, beverages, and excursions are additional. A drink package can add $50–$80 per person per day, and specialty dining costs extra. According to Cruise Critic (cost analysis), optional packages can increase the total by up to 30%. Travel insurance is another cost worth factoring; read our Insure and Go Travel Insurance Review for guidance.

Comparison to other cruise ships
Six ships, one pattern: Symphony sits in the middle of the Oasis-class lineup in both size and price.
| Ship | Gross Tonnage | Capacity (double) | Year |
|---|---|---|---|
| Symphony of the Seas | 228,081 | 5,518 | 2018 |
| Wonder of the Seas | 236,857 | 5,734 | 2022 |
| Utopia of the Seas | ~236,000 | 5,668 | 2024 |
| Oasis of the Seas | 226,838 | 5,484 | 2009 |
Trade-off: Symphony’s age means lower prices than newer ships, but it still delivers the same Oasis-class experience.
What is special about Symphony of the Seas?
Unique onboard attractions
- Ultimate Abyss: the tallest slide at sea, plunging 10 decks (Expedia).
- Twin FlowRider surf simulators (Expedia).
- Broadway shows including Hairspray (Expedia).
Entertainment options
Seven distinct neighborhoods — Central Park, Boardwalk, Royal Promenade, and more — each with its own character (Royal Caribbean Official). The ship also offers laser tag, a climbing wall, and an ice-skating rink.
Dining and amenities
Over 20 dining venues, from complimentary main dining rooms to specialty restaurants like Chops Grille and Wonderland. The Ultimate Family Suite spans 1,134 sq ft interior plus a 212 sq ft balcony (CruiseDeckPlans).
Can you live on a cruise ship for $30,000 a year?
Cost breakdown of living on a cruise ship
The $30,000 figure comes from a viral YouTube video titled “It’s ONLY $30,000 To Live on a Cruise Ship!” (YouTube (viral content)). However, that estimate does not match Symphony of the Seas pricing. At $700–$1,500 per person for a 7-night cruise, a full year of weekly cruises would cost $52,000–$111,000 per person — not including extras.
Feasibility for Symphony of the Seas
Even the most budget-friendly interior stateroom at $700/week adds up to $36,400 per year — above $30,000. Adding gratuities, drinks, and excursions easily pushes the annual figure above $50,000.
Alternatives for long-term cruising
The World, a residential cruise ship, offers private residences starting at several million dollars and monthly fees in the thousands. For a more affordable option, consider back-to-back cruises on older, smaller ships.
The $30,000 living-on-a-cruise-ship dream is a myth for Symphony of the Seas. A solo traveler would need at least $50,000 per year for the cheapest continuous stateroom, and couples face double that.

What passengers say
“The Ultimate Abyss is a must-do, but the lines can be long during peak hours.”
— Multiple reviewers on Cruise Critic
“The variety of dining options is incredible — something for every palate.”
— Cruise Critic passenger review
“It can get crowded on sea days, especially around the pool and buffet areas.”
— Cruise Critic passenger review
“Washy washy is a fun reminder to keep your hands clean, and crew enforce it playfully.”
— Cruise Critic (health guide)
What this means: Passenger reviews are overwhelmingly positive about the ship’s activities and dining, but the main complaint — crowding — is a direct consequence of carrying over 5,500 passengers. For someone prioritizing quiet relaxation, a smaller ship might be a better fit.
