Put the page where the question starts.
Slip the rigid card into the bag's document sleeve or keep it with the handle. When a helper asks for the agreed meeting point or contact route, the card gives them a clear place to start. The linked page belongs to the parent and the service they choose.
Share only the useful part.
Add selected support contacts and practical logistics. Keep medical records, clinical instructions, account details, access codes, and anything the wider support circle should not see in appropriate private systems. Ask each person before sharing their contact information.
Give the page an owner.
Choose one adult to maintain the page and test the tap after setup. If the plan changes, update the destination and test it again. The card opens the page; the page owner and service decide what is there and how it is shared.
