10 tips to save on your car rental in and around Key Biscayne

  1. Use filters to find the right car: Refine your search by selecting vehicle type and desired features. Whether you're looking for an SUV to accommodate extra passengers, a convertible for summer drives, or an economical car for budget-friendly travel, utilizing filters on Expedia will help you discover the perfect option for your journey.
  2. Book in advance to help lower costs: Rental rates can vary based on demand, so it's advisable to reserve your vehicle well ahead of your trip. Booking early often yields lower prices and greater availability, particularly during peak travel seasons.
  3. Consider a smaller car for savings: Compact cars are typically more affordable to rent and easier to navigate in crowded areas. Mid-size vehicles strike a good balance between cost, comfort, and fuel efficiency.
  4. Age guidelines: Drivers under 30 may encounter higher deposits or daily fees, and certain vehicle categories—such as SUVs or luxury models—might not be accessible. This can also apply to renters over 70 years old. Always verify age restrictions before making a reservation.
  5. Check fuel policies: Some rental agreements stipulate a full-to-full fuel policy, meaning you must return the vehicle with a full tank to avoid additional charges. This is usually the most favorable option. Other agreements might provide full-to-empty or prepaid fueling choices, which are acceptable as well, but ensure you return the car empty in such cases.
  6. Save on city and airport pickups: Picking up your rental car at the airport often incurs a surcharge, but the convenience may justify the extra cost.
  7. Know your payment options: Most car rental companies exclusively accept credit cards for payment.
  8. Understand your insurance coverage: Car rental insurance can help you avoid unexpected expenses and provides peace of mind in case of unforeseen circumstances during your trip. Adding car rental insurance is straightforward when booking through Expedia.
  9. Consider unlimited mileage: If you have long road trips planned, look for rental options that offer unlimited mileage to prevent additional charges.
  10. Bring your driver's license and ID: A valid driver's license is necessary to rent a vehicle.
