If you plan to share driving duties during your St. Thomas trip, you will need to add additional drivers to your rental agreement from Alamo, Enterprise, or National. Here is how additional driver fees work at Cyril E. King Airport (STT).
What Is an Additional Driver?
An additional driver is anyone other than the primary renter who will operate the rental vehicle. All additional drivers must be registered on the rental agreement at the counter. Driving a rental car without being listed on the agreement can void your insurance coverage.
How to Add an Additional Driver
The additional driver must be present at the counter at the time of rental with a valid driver's license. They will need to present their license and meet the same age requirements as the primary driver. You cannot add a driver over the phone or after leaving the lot.
Additional Driver Fees
Additional driver fees vary by brand and program membership:
- Alamo Insiders: Spouse or domestic partner added free
- Enterprise Plus: Spouse or domestic partner may be added free
- National Emerald Club: Spouse or domestic partner added free
- Non-members: Typically $10-$15 per day per additional driver
Who Can Be Added for Free?
Across all three brands, spouses and domestic partners of the primary driver are often added at no charge when the primary driver is a loyalty program member. Check with your specific brand for current policies.
Why Add Additional Drivers?
- Sharing driving on St. Thomas's left-side roads reduces fatigue
- Flexibility if the primary driver becomes ill
- Safety on long island drives
- Legal requirement — only listed drivers are covered by insurance
Tips for St. Thomas Travelers
Join the free loyalty program of your rental brand before your trip. This can save you the daily additional driver fee for your spouse. National Emerald Club is particularly valuable for this perk.
