family of 4 needs transport from airport - recommendations please
I recommend Golden Air Shuttle - tel. 011 33 01 34 10 12 92, in RS Paris book. Call them when you arrive at CDG to confirm where to meet, will probably take about 30 minutes for them to arrive.
For four people, you can also call for a "grand" taxi - a minivan style taxi.
Please be aware that generally cab drivers in Paris don't have to take four and often refuse to. So, if you need a cab, call for one well ahead of time.
If you choose to take a taxi rather than a private shuttle, you should find both standard taxis and minivan taxis ready and waiting at the airport.
