OK, it's about 7:30 am London time, but my brain is saying "2:30 am, go to bed". We are in Heathrow and like Rohit and Chris said, it's evil. According to Dad, someone could get lost in here and never be seen again. With his navigation skills, that will be us. We are now trying to find a place to get our London Passes. I feel like I'm about to fall asleep.
