KubeCon Europe as the main reason, with extra days to actually enjoy the city instead of living in the conference center.
KubeCon
The usual mix of deep technical sessions, hallway conversations, and the occasional overly crowded booth. Amsterdam as a host city worked well — easy to get around and enough good food options near the venue.
The City
Used the extra days to walk the canals properly, spend time in the Jordaan, and revisit a few favorite museums without rushing. Classic Amsterdam, but without the summer crowds.
