I will pop in , be interesting to see if there is more a/c on display. I seem to recall from the email updates from the organizers, there is a US Pavilion there so maybe it might be more than two halls.
I seem to recall (probably on previous thread two years ago) that initially it was some of the OEMs had influenced the push to the Thames due to easier access from LHR, LGW than hassle of coming up to my neck of the woods.
Laughingly or not, post show, there were concerns about personal security - worries about being on public transport late at night in that part of the City. Plus one of the vendors mentioned it was far easier to find and fight for accommodation in my area of academia than what it was in London...surprisingly.
Cheers and see you all around there,
