I am flying CDG-DOH-JNB-DOH-OTP with QR. After the CDG-DOH leg i'll probably poke around the city. Can I come back to the airport to sleep in one of the rooms in the lounge before my morning flight to JNB? Also, after arriving JNB-DOH, there is a place to sleep in the lounge before continuing on the OTP 8 or 10 hours later? Thanks. All flights in J.
