At CDG today with a long layover (IAD-CDG-SIN), and used the Arrivals Lounge before heading to Paris to enjoy part of the day in the city. What everyone has said before is accurate.
- It's a long hike, and 2C looks more like a bus station than an airport terminal.
- It has lots of showers. We had no wait as we arrived.
- There's breakfast. But remember, this is France, so the breakfast is continental, and the breakfast area is small.
If you want to grab a shower before you head into the city, this is your place. If you're looking for an interesting lounge experience, you'll be disappointed. This is nothing like VA's Arrival Lounge in LHR.
