DebConf7/GoodyBag

[edit] Plan/ideas

Get free branded bags from a major sponsor, and fill them with:

Tourist information, including city map (free from tourist board)
Conference timetable, only including details that are definitely fixed
Conference contact details sheet (addresses/phone numbers for venues and the like)
Food tickets (if applicable)
Conference t-shirt, in person's chosen size (may be cheaper to print in Mexico and ship over?) (optional)
Name badge
UK plug adaptor (should be possible to get ones for European and US plugs in bulk) (optional)
If we find a friendly supplier, a miniature bottle of whisky has been suggested (but we shouldn't spend a noticeable amount of money on this, people can buy their own alcohol)
Tablet would be very cheap to include (almost all geeks seem to like sugary sweets)
Conference proceedings (optional)
