The Perl Toolchain Summit will be held in
Campanile Lyon Centre Part-Dieu.
It's located 31 rue Maurice Flandrin, at La Part-Dieu.
The
Campanile Lyon Centre Part-Dieu
is also the "hackathon hotel", allowing hard workers to easily switch from their room to their "office".
(Proximity of the work place and hotel was a request from the previous editions).
It is located in front of the railway station La Part-Dieu.
The airport is Lyon Saint-Exupéry (LYS).
The Rhônexpress shuttle from the airport makes for an easy ride to the Part-Dieu station (the stop is right between the train station and the hotel). Shuttles depart every 15 minutes, and the ride takes less than 30 minutes and costs €15.90 for a single and €75.50 for a return ticket. You can buy tickets in advance at the official website, at the vending machines in the station, or even in the shuttle itself (but with an extra charge).
A taxi to Part-Dieu would cost about €50, for about the same transit time, so it's only really worth it if there are 3 or 4 people sharing the ride.
The Lyon Part-Dieu train station is literaly across the street from the hotel.
The train station has two exits: make sure you exit on the side of platform K. You should see the hotel across the tram lines and the car park from the station.
Lyon has a dense public transport network consisting of bus, trolleybus, tram, and metro. For most of the hackathon-related commutes, everything should be in walking distance. Official website of Transports en Commun Lyonnais.
