10 tips to save on your car rental in and around Groton

1. Use filters to find the right car: Refine your search by vehicle type and features. Whether you're looking for an SUV for added space, a convertible for summer drives, or an economy car to save money, utilize the filters on Expedia to find the perfect vehicle 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 car well ahead of your trip. By booking early, you’re more likely to secure lower prices and enjoy better availability, particularly during peak travel seasons.
3. Consider a smaller car for savings: Typically, smaller cars are more affordable to rent and easier to maneuver in crowded areas. Mid-size options strike a nice balance between cost, comfort, and fuel efficiency.
4. Age guidelines: Drivers under 30 may encounter higher deposits or daily fees, and certain vehicle types—such as SUVs or premium models—might not be available. This could also impact renters over 70 years old. Always verify the age requirements before making a reservation.
5. Check fuel policies: Some rentals operate under a full-to-full fuel policy, which means you must return the vehicle with a full tank to avoid additional charges. This is usually the most favorable option. Others may offer full-to-empty or prepaid fueling options, which are also acceptable. Just ensure you return the car empty in that case.
6. Save on city and airport pickups: Picking up your rental car at airports often incurs a surcharge, but the added convenience may be worth it.
7. Know your payment options: Many car rental companies only accept credit cards for payment.
8. Understand your insurance coverage: Car rental insurance can help you avoid unexpected costs and provides peace of mind if something goes wrong during your trip. It's simple to add car rental insurance when you book through Expedia.
9. Consider unlimited mileage: If you're planning long road trips, look for rentals that offer unlimited mileage to steer clear of extra charges.
10. Bring your driver's license and ID: A valid driver's license is necessary to rent a car.
