…“to be making that one having only got in at 4am” : sounds like you all are passionate about bonsai discussions to talk about trees the whole night … this is what we call “dedication” 
Already bought my 2-day tickets to take my time to attend some discussions, go through all the commercial booths & the expo. I like to visit the expo at different moment, and changing the way I visit it: I see different perspective, notice things I haven’t notice in the previous tour. Will only attend demos to say hello even if the setting does not allow for some proximity as I challenged overall demos concept here What about innovating in Demos during exhibitions?
