Cheap Alamo Car Hire Deals at Shannon Airport, SNN

Research fuel prices in the area where you'll return the vehicle. Filling up at a local station may be cheaper than paying for fuel through the rental company, especially if they charge higher rates.

Be aware that some rental companies impose age restrictions or additional fees for drivers under 25. Make sure to check the company’s age policy when booking.

Before your trip, confirm if your rental includes roadside assistance. This can be crucial in case of breakdowns or emergencies during your rental period.

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.

To save on refueling costs when departing from Airport, look for deals with a 'full to full' tank fuel policy, or even better, a free tank fuel policy, as opposed to a 'half-full to full' one.

Allow for possible delays at the rental desk, particularly during busy travel times.

Have your driver’s license, credit card, and rental confirmation ready to speed up your pickup.

If sharing driving responsibilities, check the policies regarding additional drivers. Some companies charge fees for each extra driver, while others may include it for free under certain conditions.
