Allow for possible delays at the rental desk, particularly during busy travel times.

Before finalizing your booking, check if the rental company offers free cancellation. This can provide peace of mind if your travel plans change unexpectedly.

Before renting a car, check if your personal car insurance covers rental losses. Many personal auto insurance policies and credit cards offer coverage for rentals, which could save you from extra insurance fees.

Before your trip, confirm if your rental includes roadside assistance. This can be crucial in case of breakdowns or emergencies during your rental period.

Before returning the vehicle, clarify the return procedures with the rental company. Knowing where to drop off the car and any required inspections can streamline the process.

If returning your rental at the airport, be aware of the parking policies and any fees involved.

Opt for a pickup location near your arrival terminal to minimize time spent locating your vehicle.
