I like booking trips at the last minute. Finding yourself on a plane going somewhere you didn't expect to go when you woke up that morning is a great feeling. So I was extremely happy that when I asked ESO if I could go to a conference in Switzerland, they didn't actually confirm my flights until the day of departure. I'd assumed that the flights had not been booked until I got an email at 10am telling me I was flying at 5pm. So I packed up and went to the airport in a fantastic mood.
The conference was in Switzerland but I went to London first to work at UCL for a week. It was pretty awesome to be back but after the epic feeling of arriving home after a year away that I'd had in September, arriving back again in October after three weeks away really wasn't quite the same.
