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

1. Use filters to find the right car: Refine your search by selecting the vehicle type and specific features you need. Whether you're looking for an SUV for extra space, a convertible for summer enjoyment, or an economical car for budget-friendly travel, utilize the filters on Expedia to help you discover the perfect match for your trip.
2. Book in advance to help lower costs: Rental prices can vary based on demand, so it's advisable to secure your reservation well ahead of your trip. By booking early, you are likely to obtain lower rates and enjoy a wider selection, particularly during peak travel seasons.
3. Consider a smaller car for savings: Smaller vehicles are typically more affordable to rent and easier to navigate in crowded areas. Mid-size rentals offer a good compromise between cost, comfort, and fuel efficiency.
4. Age guidelines: Drivers under 30 may encounter higher deposits or daily fees, and certain types of vehicles—such as SUVs or luxury models—might not be available. This can also apply to renters over 70. Always verify the age requirements before making a reservation.
5. Check fuel policies: Some rental agreements require a full-to-full fuel policy, meaning you need to return the car with a full tank to avoid additional charges. This is often the most economical option. Other policies may include full-to-empty or prepaid fueling options, which are acceptable as well. Just 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 this added convenience might be worth the extra cost.
7. Know your payment options: Many car rental companies primarily 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 events during your trip. It's easy to add rental insurance when booking through Expedia.
9. Consider unlimited mileage: If you plan on taking long road trips, seek out rentals that offer unlimited mileage to avoid incurring extra charges.
10. Bring your driver's license and ID: A valid driver's license is necessary to rent a car.
