Common Mistakes to Avoid
⚠️
Skipping insurance check
Many credit cards provide primary or secondary rental car coverage. Check your card benefits before paying the rental company's daily insurance.
⚠️
Ignoring fuel charges
Rental companies charge 2-3x the pump price if you return without refueling. Always refuel at a gas station near the drop-off location.
Frequently Asked Questions
Is rental car insurance necessary? ▾
Check your personal auto insurance policy (may extend to rentals) and your credit card benefits. If both cover you, you can decline the rental CDW/LDW. Always confirm before renting.
Cheapest days to rent a car? ▾
Weekdays are typically cheaper than weekends for leisure rentals. Pick-up and drop-off at off-airport locations often saves 15-25% vs airport locations.
Rental vs Uber/Lyft comparison? ▾
For city stays with good transit: Uber often wins. For road trips, suburbs, or national parks with no transit: car rental almost always wins on cost and flexibility.
