Add event conference details

I need the conference details added to Wednesday's product launch rehearsal with the cross-functional team. Edit that event to include the rehearsal room name, building address, and a one-line note about where the projector is located. Make the details visible to all guests and add a 15-minute buffer before and after the meeting for setup and debrief.

Before I paste conference logistics into the invite I will send to 30 people, make it easy for them to find the place and equipment. Put the room and exact entrance address at the top, add transport options and parking instructions, bold the AV note about the projector, and flag anything that would make a reviewer hesitate to attend in person — like no-guest policy or security check-ins.

I updated the rehearsal invite with room 412 but the team is supposed to be in 314, and some people bought parking for the wrong lot. I can correct the event and notify guests, but I'm worried about late arrivals and annoyed vendors. What is the least-damaging way to correct this now, and what immediate message gets people to the right room without causing confusion?

Across projects I keep spending hours correcting where rehearsals and launch events actually happen because I paste partial addresses or forget AV notes. Where is that time and credibility leaking from my workflow, and what habit or template should I build so every event has clear room, entrance, parking, and AV info by default?
