When comparing a taxi vs the RER from CDG to Disneyland Paris, the true cost is rarely the number you first see. A single RER ticket is undeniably cheap, and for a lone traveller it is the obvious budget choice. But a private taxi is a single fixed fare for the whole vehicle — from €70 — and that distinction changes the maths completely once more than one person is travelling. The headline price of the train is per head; the headline price of the taxi is per car.
This guide compares the two honestly on what they actually cost a real traveller, including the things people tend to leave out of the sum: tickets for every family member, the time lost to a change with luggage, and the value of arriving directly. By the end you should be able to work out which genuinely costs you less.
The true cost of the RER from CDG
The RER route runs RER B from the airport into Paris, then a change to RER A at Chatelet-Les Halles out to Marne-la-Vallee/Chessy. The fare is paid per person, and children pay too beyond a young age, so a family of four buys four tickets. The journey takes 60 to 90 minutes door to door once you add the walk to platforms, the change, and waiting time. The ticket price is low, but it is not the only cost: an hour and a half with cases and tired children carries a real, if unpriced, toll.
The true cost of a private taxi
A private taxi is quoted as one fixed fare from €70 for a saloon carrying up to three passengers, or more for a minivan seating seven to eight. There is no meter, so traffic does not inflate it, and no per-person charge — the fare covers everyone in the vehicle. The drive is direct, around 45 minutes, with luggage carried and free child seats fitted. Book a return at the same time and you take 10 percent off the round trip. Crucially, the price you are quoted is the price you pay.
Compare the real numbers for your trip
A single fixed fare from €70 covers the whole car, direct in about 45 minutes. For a family or group, that often beats several RER tickets once the saved time is counted.
Where the break-even point falls
For one or two budget travellers, the RER wins on raw cost. The picture shifts with group size. A family of four buying four rail tickets often finds the gap to a single taxi fare surprisingly small, and a group of six to eight sharing a minivan can pay less per head by taxi than they would on the train, while saving the change and the luggage struggle. The break-even point varies with the day, but the rule of thumb is simple: the bigger the party, the more the taxi makes sense. Our full RER versus taxi comparison explores this in depth.
Counting the costs people forget
The fairest comparison includes the costs that never appear on a ticket. With the RER, that is the time and energy of a change at Chatelet with suitcases, the lack of a door-to-door drop, and no allowance for a delayed flight. With the taxi, the fixed fare already absorbs flight tracking, free waiting, meet-and-greet and child seats. For groups especially, our group transfer service spreads one fare across the whole party. Whichever you choose, knowing the full cost — not just the cheapest single ticket — is how you make the right call.
Frequently asked questions
What is the true cost of a taxi vs the RER from CDG to Disneyland?
The RER is cheapest per single ticket, but a private taxi from €70 is one fixed fare for the whole vehicle. Once a family buys several rail tickets, the gap narrows sharply.
How much is the RER from CDG to Disneyland Paris?
The RER needs RER B into Paris then a change to RER A out to Marne-la-Vallee/Chessy, paid per person. Children pay too beyond a young age, so a family of four pays four fares.
Is the taxi worth the extra cost over the RER?
For families and groups, usually yes. The taxi is direct in about 45 minutes with no changes, free child seats and luggage carried, against 60-90 minutes and a change on the RER.
At what group size does the taxi become cheaper?
As a rough guide, a family of four or more often finds a single fixed taxi fare comparable to or cheaper than four-plus rail tickets, once saved time and effort are counted.
Are there hidden costs with the RER?
Easy to overlook rather than hidden: tickets for each traveller, the time cost of a change with luggage, and no door-to-door service. The taxi fare is all-in and fixed.
