Anyone know the best way to get from Orly airport, where we will be arriving from Toulouse, to the Holiday Inn Roissy, which is adjacent to the Charles DeGaulle airport, for our trip home?
The best way, depending on timing, is probably the Air France bus service that runs directly between the two airports. While it can get caught in traffic, at least there are no transfers. See www.cars-airfrance.com and click on "line 3" after selecting English for times and fares. The other way is to take the driverless OrlyVal shuttle train to the RER station, then catch an RER regional train headed for CDG airport...it'll take you right through the center of Paris, mostly underground. Then catch the hotel's shuttle (I assume they have one) from CDG.
