We will be arriving at 5:30am CDG airport in terminal 2E which has all the shops and then we need to go to terminal 2F to catch our connecting flight to Rome. we have almost 1.5hours to kill. Last time i recall shops at terminal 2E were closed because it was too early. Can we hang around that terminal until shops open before we go to the smaller terminal 2F? I know there are shuttle buses which i think would take about 10 minutes to get to next terminal. Does anyone know what time those shops open? and is a 10 minute shuttle ride reasonable?
