Public transport from CDG to Courtyard by Marriott Coulmbes

We are couple who need to get to the Courtyard by Marriott at Coulmbes near La Defense from CDG on Thursday. We land at 5.30PM.

Which is the best public transport that I can avail?

No heavy luggage with us so we can take bus/metro.

Thank you

%26quot;... If you are taking public transportation from Paris France CDG airport to the Colombes Paris Hotel, France, take the rapid rail trail %26quot;RER B%26quot; downtown station called %26quot;Chatelet - Les Halles%26quot;, then change to take rapid rail train line %26quot;RER A%26quot; to %26quot;La Defense%26quot; station in the West of Paris, France. From here there are buses (lines 161, 262 or 272) that all stop right across the street from the Courtyard by Marriott Paris Defense West - Colombes at the %26quot;Buffon%26quot; bus stop ...%26quot;

... or spring for a taxi at least for the inbound trip...
