Verify the meeting place, not just the street
If the organizer moves rehearsal from the main hall to the annex, open the new address on a map and compare it with their written instructions. Replace the old pin in the household record. If the entrance is unclear, share the confirmed street address and mark the entrance as unknown. Ask whether the annex uses a separate entrance, street number or pickup point. A pin at the center of a campus may be less useful than a confirmed door name.
Change the whole event record
Check the written location, map link, notes, travel reminder and any shared message that contains the old address. Replace the outdated link where people usually open directions. Include the organizer’s confirmation and tell travellers already en route what changed; they may be following a saved route that will not update itself.
Give people a fallback on arrival
Use a stable landmark or agreed contact rather than a vague instruction to “look around the back.” If the organizer can confirm only the building, say exactly that and arrange a meeting point outside. Do not invent an entrance to make the directions look complete.
