I think it very much depends where you are. New Zealand could likely do in-person events this year while other locations would struggle with capacity limits just for starters (it’s not only capacity in total but capacity and distancing in breakout sessions and cleaning in between)

I volunteer with a local performing arts organization, we aren’t going to do an in-person event until 2022 because of the capacity limits, enforcing mask requirements and distancing, and other things that fall to volunteers. We already have people who won’t mask up at the grocery store and harass employees, now some poor volunteer has to deal with them? We rely on and like our volunteers too much to do that to them.

I think there’s an ROI to be considered here, but let’s talk beyond money and call it a ROHI—return on human investment. The event is only worth it if it’s not overly burdensome and stressful on the volunteers organizing, running, attending. I’m not sure that’s going to be true (in the US at least) until late 2021 at the earliest
