The Airport Rent-A-Car Center is at 7135 Gilespie Street, about three miles south of LAS. Take the free rental-car shuttle: Terminal 1 Level 1 outside doors 10–11, or Terminal 3 Level Zero at either end. The airport says its rental-shuttle fleet is ADA equipped.
Check whether your company is at the center. Some off-site agencies need a second transfer from the center; read your confirmation instead of heading straight for a terminal counter.
Budget for the shuttle wait, ride, rental queue, and vehicle collection. An extra 45–60 minutes is a useful planning allowance, not a guaranteed completion time; busy periods can take longer. Check the rental total for airport charges, taxes, insurance choices, extra drivers, age-related fees, fuel terms, and deposit requirements. Add your hotel’s parking cost before deciding that a car is cheaper.
Returning: navigate to the rental company’s return at the center, then take the shuttle to the correct terminal. Refueling, inspection, and the shuttle happen before your airport check-in window. Allow a separate 45–60-minute return margin on top of the drive and your airline’s airport arrival target, with more room during roadwork.
