The detail to resolve first
A useful first message contains a local date and time, full pickup and destination, passenger count and luggage. If one detail is undecided, say so. A short structured brief is easier to confirm than a conversation containing several conflicting addresses.
Prepare a workable enquiry
Keep the full address, local travel date and travelling passenger’s contact together. Mark fixed deadlines and any special requirements. If another person makes the booking, decide who receives the final instructions.
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.
