Break out sessions should accomodate more people .physical participant shd not attend breakout sessions on zoom.
Lunch break and tea break shd be enough for all participants and technical people on ground once you have a tag to get into the conference room.
Virtual participants shd also have packs no matter how small like it was done when hybrid conference started and they should also be allowed to partcipate in raffledraw even if it is only consolation prizes.
Recorded audio and video coverage should be made available for sale or there should be a site once can have access after the event.
