Write every cost
List outbound and return transport, room nights, meals, local vehicles, guide, entry fees and small transfers. Keep a reserve for delays or a changed return route. Use Trip planner to record your own confirmed amounts.
Build a realistic trip budget
Separate shared costs from per-person expenses.
Compare like for like
Compare a room price per night with the same occupancy and taxes. Compare meal prices per person and transport per journey or whole vehicle. Do not divide individual tickets as though they were a shared vehicle cost.
Keep evidence
Ask for a written quote and cancellation terms. Record deposits and remaining payments with receipts. Current fares change; a sample budget is a planning estimate, not a promised sale price.
