One more thing!
We'll be staying at 'Only suites' hotel near the cdg airport for a night. Would a taxi ride to disneyland cost too much for the 3 of us? The other option is the rer? Or a bus?
I'm thinking if the stops aren't near the hotel we'll have a lot of luggage to carry. This is also my concern from disneyland to Paris. It would be difficult to walk in the heat with a child and luggage to find a bus stop or a metro stop.
