Whoops, forgot to tell you we are flying BA.
Had assumed it would make more sense just to spend the night near Gatwick and then go to Heathrow the next morning. Our plane leaves about noon I believe.
I also just learned that my daughter (22) will be overnighting at Heathrow as well ALONE, so now the issue of personal safety comes into play as well on a grander scale. Jamiel, the "ghost town" bit makes me nervous. Need I be concerned?
