What is the quickest route from the Charles De Gaulle Airport in Paris to the Hotel Malar?

My wife and I will be traveling to Paris for our honeymoon. What is the quickest way from our the airport, Charles De Gaulle, to our hotel, Hotel Malar. We would also appreciate information on how to get back to the airport, as we will be traveling to Ireland as well.

The fastest route by public transportation would be to take the RER B from the station that is in the airport to the Saint-Michel Notre-Dame and change to the RER C line (Direction : Boulevard Victor) and take it to the Pont de l'alma station.

The cost will be 8.40 euros per person and the time will be 48 minutes plus a walk of under 10 minutes from the station to your hotel.

Depending on the time of day a taxi would not likely be very much faster and would be considerably more expensive.

To reverse the route to return to the airport simply take the RER C from the Pont de l'alma station (Direction : Versailles-Chantiers) to the Saint-Michel Notre-Dame stop and transfer to the RER B (Direction : Aeroport Charles de Gaulle 2 TGV).
