I'm arriving CDG 2E in two weeks, on a Wednesday morning (8:35am arrival). What do you all think is going to be the fastest and easiest way into the city? Will the RER take much more time than a taxi? I'm going to the 7th arr.

Never done RER before. Always taken a taxi, but I'm alone this time, so curious if better way than a taxi. I'll have one roll-aboard carry-on and perhaps a laptop bag. And I speak fluent French.

Thanks!

BTW, how long does immigration usually take at 2E?
