I suspect I am working in the wrong time zone or something (it's 03:20).
The result of Prague or Amsterdam seems reasonable, though the total number of votes now seems rather high! Due to the 'interested' nature of recent posts on Prague, and the lack of people complaining about it in the last day or so, I suggest we are going to Prague.
The date
poll comes out showing 18th.May as the most popular weekend and certainly indicating the last part of May as most practical for numbers.
Result:
Prague during the weekend of 18th.May 2013.
After a short pause for sleep, there will be a thread for hints and tips from all those concerned over what we might want to do and see, where we may stay, how we may travel and so on.
