ETHBrussels and Brussels Blockchain Week
The Belgian week is quiet right now, but the reason to fly in has not changed: the EU institutions are here, and so is everyone lobbying them.
For the people who fly in to work. The flight, the venue, the taxi, the deck, the call and the dinner, on one line.

Evidence
Two to three devices per attendee, and log-ins alone spike past a thousand at once.
rottenwifi.comExhibitors reported the Wi-Fi dropping every time footfall peaked. Reported as the pattern at nearly every large venue.

A person, not a bot loop, for the whole trip.
Why
A Brussels trip is usually a Brussels, Paris and Amsterdam trip, and one plan covers all three
The hackathon venue is a coworking floor, where every team is on the same Wi-Fi at once
Eurostar and Thalys are working hours, and onboard Wi-Fi is not
Belgian roaming rules protect EU residents, not visitors from outside.
Local knowledge
BeCentral sits above Brussels Central station, which is ten minutes from the airport train and walking distance from the Grand-Place.
Cards, including contactless, nearly everywhere. Bancontact is the local scheme and is domestic only.
ethbrussels.com now redirects to a link page that says June 9 to 11 at BeCentral with no year on it. We are not printing a year we cannot source.
The plan covers 33 countries, so the Paris and Amsterdam legs are the same eSIM.
