Hi Jellifer, your staying at PI, at terminal 4, how do you get to the other terminals from there? Do you use the connection train? I'm asking because I usually stay at the Thistle hotel near terminal 5. And I think I might book the PI at terminal 4 for my next trip. When at the Thistle hotel near, terminal 5, I have to get either a taxi or use the pod to get to terminal 5, then get the connecting train. So any info would be helpful
