Hi,

As far as I can tell, the role of the local organizer would be to

   - Create a guide for attendees in terms of getting around, things to do
   etc
   - Help a in some cases with the visa requirements for different countries
   - Potentially act as a liaison with local authorities

I'm not sure how this splits across assistants, but this is what I know
so far.
Indeed, the hot period would be something like April to end of July.

Best,
David
