The four stages of CES
Stage 1: Denial
Set up every possible appointment you can. That's the whole point of a conference, right?
Stage 2: Shock
Sudden realization that you might not have much time to walk the show floor, eat or go to the bathroom because you've set up too many appointments.
Stage 3: Bargaining
Running progressively later for appointments, make apologetic phone calls, try to rearrange schedule.
Stage 4: Acceptance
Brazenly skip every other appointment; use the extra time to run to remaining appointments.
