Travel costs can creep upward when several smaller expenses are added after the main bookings have already been made. Anyone preparing for the DRC can review the [ information before setting a final trip budget. I’d keep visa-related expenses on the same planning sheet as flights, accommodation, insurance, and transportation. That makes it easier to see the full picture instead of focusing only on the biggest payments. Checking the applicable information near the time of application is also a sensible step, particularly if your initial travel research was done well in advance.
