OMG what a huge airport is Heathrow. I had 4 hours between flights and only had an hour to sit and read before heading to Dublin. By the time you go through immigration, security and then change terminals and go through most of that again, then walk miles (25 mins) to departure gate. Bill would not have coped with it.
Yes Ireland is really green. Tomorow I will go out wandering and put some photos up.
