Hello,
I guess this is actually several questions...
We're arriving CDG Sept 26th a.m. from Seattle (Northwest Airlines). I thought I saw a post somewhere that had clues on how to tell which terminal you're coming into. We're looking at doing the Renault car lease and need a hotel in Paris for that first night (as well as our last night Oct 12th). Trying to coordinate the hotel with the airport and car pick up (pick up spot says Roissy/CDG). Sightseeing Paris that first day (have to figure out subway into city) and actually not picking up car until morning of 27th - definitely want them all close. Thanks for your help!
