Whilst exact dates for unannounced workshops I'm sure will be announced closer to the due dates, for the purposes of planning ahead with vacation time from work (i.e. ensuring that it is available), is it possible to get at least 1 or 2 month windows on when some of them will be? Whilst workshops may only be 6 or 7 days, depending on where they are relative to where you live relative to the location, a day or two either side can disappear to travel meaning that taking a longer vacation is a better use of time.
