What a week in Paris
actually costs a family of four.
$4,500 to $7,000 all-in, flights included, for two adults and two kids flying from Boston and staying in an apartment with a kitchen. That is a real range to plan around, not a quote, and here is exactly what is inside it.
One week, roughly $4,500 to $7,000.
Round-trip Boston to Paris (CDG) for four seats, based on typical economy fares of roughly $650 to $900 per seat, less in fall, more in peak summer.
A one-bedroom to two-bedroom apartment with a kitchen, which is the lodging style this whole cost model assumes.
A mix of cooking in the apartment kitchen and eating out, which is what actually keeps this line from running away.
Metro passes, entry fees, and the occasional paid activity. Most museums are cheap or free for kids, which keeps this the smallest line in the budget.
Lodging, not the kids' meals.
Kids do not add cost evenly. Lodging is the real lever: two adults and one or two kids fit a studio or one-bedroom apartment, while a third or fourth child usually forces a two-bedroom, which is the single biggest jump in the whole budget. Flights scale predictably, a child under 2 flies as a lap infant for very little, and every child 2 and over needs a full seat at roughly the same fare as an adult. Food rises gently rather than sharply, since younger kids share plates and only the older ones eat a full meal.
Rule of thumb from Boston: one more child is roughly one more flight seat plus a step up in apartment size. That is the bulk of what changes.
What families ask us.
How much does a week in Paris cost for a family of four?
Roughly $4,500 to $7,000 all-in, flights included, for two adults and two kids flying from Boston and staying in an apartment with a kitchen. Season and how far ahead you book swing the number hugely, so treat this as a range to plan around, not a quote.
What is the single biggest cost in a Paris trip?
Flights and lodging together dominate, but lodging is the lever that actually moves with family size. Two adults and one or two kids fit a studio or one-bedroom apartment. A third or fourth child usually forces a two-bedroom, which is the single biggest jump in the whole budget.
Do kids fly full price to Paris?
A child under 2 flies as a lap infant for very little. Every child 2 and over needs a full seat, roughly $650 to $900 round-trip from Boston in economy, essentially the same as an adult fare.
Are museums and attractions expensive for kids in Paris?
Not really. Most attractions are cheap or free for children, and French national museums are free for anyone under 18, which keeps the activities line of the budget relatively small compared to flights and lodging.
