I didn't read "I was there for 10 days" to mean a "10-day" conference. CppCon has multi-days classes or workshops that extend the conference. Maybe his employer was good enough to pad the time to cover jetlag. This is something I've seen EU companies do that US companies would never do. PyCon is the longest conference event that I've encountered, but that involves pre-conference workshops and sprints after the conference. It is great to be able to immerse yourself in the community, but it can be tiring by the end.
