The detail to resolve first
Match arrivals to hotel allocations and conference start times. Separate airport collection, venue movements and evening returns into clear legs. If attendance changes, update passenger counts and vehicle groupings together rather than forwarding isolated names.
Prepare a workable enquiry
Put appointments in time order. Identify the meeting that cannot move, the person coordinating changes and the contact at each venue.
Check the written arrangement
Ask which parts of the itinerary are included, how waiting is handled and what to do if the schedule changes. Identify any tickets, guiding, specialist assistance or extra stops that require separate arrangements.
Keep the written confirmation available to the passenger. An enquiry or a WhatsApp conversation is not a confirmed reservation until the specific journey has been accepted.
