The first cruise decision is not which ship. It is which trade-offs you are willing to live with for a week — because every choice below is really a choice about what kind of holiday this is. Take them in order and the right sailing usually names itself.
1. How long: seven nights, not more
Seven nights is the industry standard for a reason. Shorter sailings of three to five nights skew to party crowds and sampler pricing; longer ones of ten-plus are better appreciated once you know you like cruising. For a first sailing, seven nights in the Caribbean or the Western Mediterranean is the control group — both run $500–800 per person interior in shoulder season, both are the densest, most competitive markets in cruising, which is where the pricing works hardest for you.
2. Big ship or small ship
Ships over 3,000 guests are floating resorts: waterparks, fifteen restaurants, Broadway shows, crowds at peak times. Ships under 1,000 are quieter, port-intensive and pricier per night. The middle — 1,500 to 2,500 guests — is where most first-timers land happily. The full argument is in big ship or small ship.
3. Which line: personality over price
The mainstream lines differ less in price than in who is on board. The gap between them is the holiday you get, not the fare you pay — families, couples, food-first travellers and party crowds each have a home. Cruise lines: who is who maps the field honestly.
4. Which itinerary: the Caribbean-Med default is fine
For a first cruise, the destination matters less than the rhythm: alternating port days and sea days, warm weather, easy ports. The Eastern or Western Caribbean from Florida and the Western Med from Barcelona or Rome are the two best-served first-cruise waters on earth, and both are priced accordingly.
5. Which cabin: inside, and spend the difference
The inside-versus-balcony question is the most over-thought decision in first-cruise planning. On a seven-night warm-weather sailing the balcony premium typically runs $300–700 per person over the week — real money that buys real pleasure, but for a first cruise the better answer is usually the inside cabin plus the excursions and dinners the saving pays for. If you hate it, you will know exactly what the balcony buys on cruise two. The full case is in balcony or inside cabin.
6. When: shoulder season
May, September and early December are the first-timer's months: same ships, same routes, 20–40% below peak fares, thinner crowds. Avoid spring break and the Christmas-New Year fortnight unless the date is the point.
7. What is actually included
Before comparing fares, know what the number excludes: gratuities ($16–18.50 per person per day), drinks, specialty dining, excursions and wifi. Two sailings $200 apart in fare can be $800 apart at checkout. The full reckoning is in first cruise: what nobody tells you.
The short version
- Seven nights, Caribbean or Western Med, $500–800 interior in shoulder season.
- Mid-size ships (1,500–2,500 guests) are the first-timer sweet spot.
- Pick the line for its crowd, not its price.
- Inside cabin first cruise; let the saving fund the trip.
- May, September, early December for the best prices.
- Compare total cost, not headline fare — gratuities and extras add $50–90 per person per day.
