I won't have my exact itinerary for Prague until two weeks before I leave home on August 31st. But I WILL be in Prague for 4 days at some stage between Sept 4th and Sept 17th so if I possibly can, I will BE there, at this show. Vienna first then Budapest then Prague then Bratislava then back to Vienna for a night before flying home, all between 1st and 20th. It will make up - partly - for not being able to go to next year's Conference.
