"Little return on investment from prior events"
This. I went to one smaller SAP event during my entire career and it was a complete waste of time. It felt like a Ted Talk where everyone just agreed with and comforted one another. I couldn't tell whether or not I was at something for work or if I accidentally walked into a Heaven's Gate meeting. A lot of people had this blank stare like they wanted to sleep but couldn't and they wouldn't stop smiling. The only thing I had to show for it was a half of a week of work to get caught up on.
