There are those times when you totally and completely luck out.
First, I managed to figure out the changes to the CME process this year so that I managed to leave with my certificate for 16 hours clutched in my hot little hands.
Secondly, the transportation to Harthof at the end of the conference went extremely smoothly. Enough so that I was able to grab the 1923 train rather than wait for 2040. Even better, the Bahn had switched trains so that everyone on the original 1923 train no longer had a valid seat reservation. I was able to grab a very nice seat, a single with a table and relax all the way to Mannheim.
Then, the nice guy came and picked me up at the Heidelberg Bahnhof – beat midnight by a couple of minutes!
