Frequently Asked Questions
Do rental car prices always drop closer to the date?
No, prices often increase as inventory decreases. However, last-minute deals can appear. Best strategy: book early refundable, then track prices.
Should I prepay for a rental car?
Only if the savings are significant (15%+) AND you’re certain about your plans. Prepaid rates often have penalties for changes/cancellations.
Is full-size worth the upgrade from economy?
Usually only $5-$15/day more, often worth it for comfort and trunk space. Compact and economy classes are often the same car anyway.
Why are rental car prices so high?
Industry consolidation, fleet shortages after pandemic, and high demand at popular destinations. Book early and use strategies in this guide.
