The train is cheaper for one or two people — an RER ticket is only a few euros each. But a taxi is a fixed fare per car (€70 from CDG, €90 from central Paris for 1–3), so for a family of three or four it is often better value, and always faster: about 45 minutes door to door versus 90 minutes-plus with a change.
Where the train wins: solo and pairs
If you are travelling alone or as a couple on a budget, the train is genuinely cheaper. From central Paris the RER A to Marne-la-Vallée–Chessy costs only a few euros per person and drops you beside the parks. The taxi cannot match that headline number for one or two people — and we will not pretend otherwise.
Where the taxi wins: families and groups
The maths flips with numbers. Our fare is per vehicle, not per person. A fixed €70 from CDG split across a family of four is well under €20 a head — competitive with train tickets once you add the change and the extra time. For three or four travellers, the taxi frequently comes out ahead overall, and you get a door-to-door ride with free child seats. When that is your situation, book your Disneyland Paris taxi and skip the platforms.
Count the hidden costs of the train
A cheap ticket is only part of the picture. From CDG there is no direct RER, so you change lines and typically spend 90 minutes or more with luggage. Add the walk at each end, the effort with a buggy, and thinning late-night services, and the "cheaper" option costs you in time and stress. Our taxi vs RER CDG to Disneyland Paris page breaks the trade-off down in more detail.
What the fixed taxi fare gets you
A set price whatever the traffic, a driver who meets you in arrivals, luggage help, free child seats and a 45-minute ride straight to your hotel. See the full pricing on the taxi fare CDG to Disneyland Paris page, then reserve your transfer if the numbers suit your group.
