Book early for peak seasonSummer and school holidays see supply tighten fast. Booking 4–8 weeks ahead typically gets the best choice and price.
Always compare fuel policiesFull-to-full is almost always cheaper than full-to-empty. Check the policy before you book.
Use a credit card for the depositMost suppliers won't accept debit cards for the security hold. Some gold cards include car hire excess cover too — check before you travel.
Photograph the car before you driveDocument any existing damage with timestamped photos before leaving the rental lot. This protects you from disputed charges at return.
Check cross-border rules in advanceTaking a hire car into another country often requires pre-approval and additional fees. Always declare your plans at booking.
Return the car on timeMany suppliers charge a full extra day for returns that are even an hour late. Build in buffer time, especially at busy airports.
