At this stage, a few weeks out, the who/what for most of my week is planned, with only a few gaps left for "hold" etc. There are still a few people to contact to arrange a meeting. But even for the confirmed meetings, the location details for many are still missing - and, from experience, will stay as "to be confirmed" until the last days before the show.
One tip that took me a few years to learn was allow some padding between meetings depending on the location. Too often in years gone by I would discover my 1600-1700 meeting was a 15 minute walk from my 1500-1600 meeting. Now I take locations into account where possible, and allow some transit time. And I try to be brutal about finishing meetings on time, however interesting the discussion.
Never underestimate that SC is hard work. But usually SC will be fun too - there will be many enjoyable social interactions and some networking opportunities in great hospitality settings.
