I agree it was a very well run show and the subject matter in the conference rooms was as vast as the slightly underused exhibition area. Getting to see and hear all you wanted to was difficult when there were three different subjects running in three different rooms at the same time! Good for teaching the management of priorities though!
On the whole it ran like a well oiled machine but there were no casual walks between venues - the coach was a required addition.
Prague was Prague, well worth a stopover. The beer? Great!
