Update: Went in there to check. Damn them. It’s now pay and display. Tenner for the day though. Might be worth it.
White Street car park in Cork is (no longer) free on weekends, if you get in there early enough. For those that register early (like 9am) then this car park would be perfect. White Street is in the bottom left of the map. Click the below map to see where it is in relation to BarCamp:
You can also see this on Google maps:
Alternatively there is a pay car park right next to Webworks.
Thanks to Terry for making the map.
