You have seen the ad: "7-night Caribbean cruise from $449!" So why did your neighbors say their cruise cost their family nearly six thousand dollars? Both numbers are real. The ad shows one person's bare fare in the cheapest inside cabin; your neighbors paid the all-in number for an actual vacation.
Here is the direct answer, as of late 2026 and in typical ranges, not quotes. A 7-night cruise on a mainstream line like Carnival, Royal Caribbean, or Norwegian typically costs roughly $500 to $900 per person for an inside cabin and roughly $1,000 to $2,000 per person for a balcony, before extras. On top of the fare, plan for gratuities of roughly $115 to $160 per person for the week, plus drinks, wifi, shore excursions, and travel to the port. A realistic all-in budget for two adults in a balcony cabin on a 7-night Caribbean sailing is roughly $3,500 to $5,500. A couple watching costs in an inside cabin can do the same week for roughly $2,000 to $3,000 all-in.
I am Christine, an independent travel advisor with InteleTravel, and I never pay a planning fee forward to you: the cruise lines pay my commission, so my job is simply to make sure the number you budget is the number you actually spend. Here is where every dollar goes.
The fare: what drives it up or down
Three things set your base fare: the line, the cabin, and the date. By line, as of late 2026, think in these rough 7-night per-person bands: Carnival often $400 to $800 for inside cabins; Royal Caribbean and Norwegian a notch higher, especially on newer ships; premium lines like Celebrity or Princess roughly $900 to $2,000; Virgin Voyages in the premium band with more included; Disney well above the pack, often $1,500 to $3,500 or more; and luxury lines beyond that but with nearly everything included.
By cabin, each step up roughly adds 30 to 80 percent: inside, then ocean view, then balcony, then suite. By date, the same ship can swing 40 percent or more between a late-August hurricane-season week and a Christmas or spring-break week. Kids' fares as third and fourth guests in a cabin are often heavily discounted, which is why cruising stays one of the cheapest family vacations per day. One more fare footnote: advertised prices are per person based on two in a cabin, and solo travelers usually pay a single supplement unless they book a studio cabin or a solo-friendly sailing.
