This is the annual convention of the World Science Fiction Society and the Hugo awards. This year (August 2019) it is being held in Dublin!
Next year will be in New Zealand. (I’m sorely tempted.)
The website for Dublin is down today, probably due to the major increase of traffic because today is the first day to reserve hotel space in their blocks.
However, in order to reserve hotel space through them, you must pay in their currency. There are definitely some pros to booking through them – some of the hotel prices are much lower because of the WorldCon rate, and the closer hotels seems to be completely booked up by the convention. However, there are a couple hotels still within walking distance that are cheaper through a Canadian travel consultant. Hint hint.
Are you interested in travelling to WorldCon in Dublin (or New Zealand next year)?
