Book Cheap Dollar Car Rental Deals in Castleknock, Dublin, Ireland

Many rental companies require payment by credit card and may not accept debit cards. If you only have a debit card, check the rental company's payment policies in advance and look for suitable options.

If you plan to have someone else drive, check if the rental company permits a second driver and whether there are extra fees involved. Some may offer free additional drivers under specific conditions.

Ensure your rental agreement, ID, and insurance details are easily accessible throughout your rental period for quick access if needed.

Make sure you know the details of the roadside assistance included with your rental. This is crucial in case of breakdowns or accidents.

Before departing, check the interior of the rental car for cleanliness and any functional issues. Ensure equipment like the radio and air conditioning works properly.

Before booking, check for any promotional offers or discounts that may be available. Many rental companies provide seasonal deals or discounts for early bookings.

If you have a specific vehicle in mind, opt for rentals that guarantee your chosen car type. This ensures that you receive the vehicle you expect, rather than being offered an alternative.

When booking, check if the rental company offers extras such as GPS or child seats. These can enhance your driving experience but may incur additional costs, so it's wise to factor them into your budget.
