You are almost there... you have your plane tickets, your extra-revised presentation slides in both electronic and paper format (having stored the electronic format in your laptop and at least two USB pendrives)... what's next? oh dear, your luggage!
Weather forecasts promise an almost sunny week with temperatures reaching 18 ºC (66 ºF). However, don't be fooled, minimal temperatures will drop to 7 ºC (44 ºF), so bring a warm coat for hanging out at night. Remember that Catania is located at the coast and humidity expands the thermal sensation.
But "Man shall not live by bread alone", there's electricity too. You may find the following plugs during the Conference:
... Type F...
... and finally, Type L. However, if you bring an adapter for Type C, it will work for the rest of sockets. At this point, I would like to ask all colleagues to avoid bringing devices like this one:
They are bulky and the worst thing is that while plugged on, they disallow the use of contiguous sockets. So please, think in the rest of your colleagues and just bring the one you need.
Finally, remember that 220V and 50 Hz is the standard power supply throughout Italy.
What else should you bring in your luggage? Oh yes, your best intentions to have a great time in Catania!
