Here's the answer if you still need it... this answer applies to
Avis and
Budget:
Renting multiple vehicles:
- Since you can only drive one vehicle at a time, you can only rent one vehicle at a time. You can be the lead on one vehicle, and your spouse can be the lead on a second vehicle. For the third, you will need to have another person, over the age of 25, rent the vehicle. Each lead renter will need to have a valid driver's license and a credit card/debit card. Even though you can't have three vehicles in your name, the amount of the rental is put on hold on your credit card until the vehicle is returned. When you go to return the vehicles, you can charge all 3 on your credit card if you would like.
- Additional Drivers: Spouses drive for free. All other Additional Drivers need to be 25+. Additional Driver fee applies for EACH additional driver. There are some exceptions to this (ie. USAA Members, some corporate customers, active military on official orders, etc...)
- Insurance: Check with your credit card/ insurance company to see what is and isn't covered. Basically, the lead driver for each vehicle has liability for that vehicle. If there is an accident, it's hard to know whether or not insurance will cover it ahead of time. If the lead driver isn't driving, their insurance may deny the claim, because they weren't driving and they don't own the vehicle. The additional driver's insurance may not cover it because they didn't rent the vehicle. Best advice is check with your insurance company and the credit card company. Find out what their policies are on Additional Drivers, Loss of Use, and Specialty Vehicle rentals (SUVs and Vans are in a different category than cars).
- Discounts on multiple vehicles: Since you can only rent one vehicle in your name, there really isn't a "multiple vehicle discount". With that said, you may be able to get a coupon or discount code from a friendly customer service agent. Generally the best rates are available through Costco or USAA.
Good Luck!
