The Siege of Leiden

Apparently on the day I’ll be arriving at Leiden (October 3rd) for WordCamp Europe the entire city will be having a huge party.. here’s what my airbnb host msg me:

Dear Nuno,
I’d like to inform you that you’ll be arriving at a regional Leiden feast day: 3 of october ‘Leids ontzet’ is a huge traditional celebration for the Leiden inhabitants (read drinking beer), and the whole city center is full of a crowd during the day but also in the evening and throughout the night….
Anyhow, I thought I’d better inform you that you may have to take a taxi from the train station to get to my house (or be lost in the crowd if you like adventure ;-)

Oh the fun awaits us!
