Saw surprisingly more ice in England recently, but generally yes, ice is rare. Draft beer is cold though unless it's the ales at cellar temperature.
Airports are airports, nothing fancy IMO. Drives me crazy that they don't announce gates at Heathrow until an hour before the flight, and when they did it was a full 20 min walk, escalators but no moving walkways or trams, and my flight was already boarding by the time I got there.
Air conditioning is rare to non-existent as well, and what's there doesn't work nearly as well as in the US.
Drove in Ireland some, roundabouts and driving on the left side in general got very interesting, but ok so long as I was following traffic. The worst part was some VERY tight roads, sometimes about a car and a half wide, with tour buses and big trucks flying around corners. I'm amazed I didn't wreck. Never drove in Germany, at least it's the right side, but the motorways in general and the no speed limit sections of the autobahn there is next level.
