Being prepared
Weather, electricity etc
Weather
During the conference the temperature will be around 11°C with highs of 15°C and lows of 8°C. It will be cloudy with a fair amount of light rain. Glorious, then. There is (much, much) more about this on the appropriate weatherspark.com page.
Electricity
Dutch Electricity was 220 volts, and then moved at a rate of 1 volt per year to the European standard 230 volts. The plugs are the fairly standard European two-pin model.
You can buy voltage and plug converters at Aurora, on the Vijzelstraat at the end of the Flower Market, near the Munt Tower.
Currency
The currency used in the Netherlands is the Euro, expressed as EUR or €.
