I asked a few days ago about what other location my friends & I should visit during a girls trip to Paris at Christmas time & you all were so helpful! I think we've decided on Colmar, per your recommendation.
With that, we'll be flying round-trip in/out of Paris (I know Frankfort could shave off 30 min or so of travel, but our flights are direct if we stick to CDG). Curious if those of you who know the transportation system there well would recommend going straight to Colmar upon arrival, ending our trip in Paris or Paris first followed by Colmar. We'll have to be at the airport around 8am when we fly out, so trying to decide if we did Colmar second, if we should stay at an airport hotel the last night (we usually do Airbnbs).
OH! And I read there is a train station within CDG.... is that the same one that we'd be taking for Colmar or just local transport?
