Cluj suits a Transylvanian route with several overnight bases. Plan driving days around visits rather than moving every night.
Confirm airport collection with the branch and supply the flight number. Ask whether the handover is at a terminal desk, meeting point or off-airport office before paying.
A car helps connect Transylvanian towns, rural guesthouses and routes away from mainline rail. It is less convenient for a Bucharest-only break. Choose rental dates around countryside travel and keep the first drive modest after a flight.
Compare airport collection with a later collection if you start with a city stay. Include the transport to a different rental branch and any extra parking nights when comparing the total cost.
