Renting a car at the airport is convenient with shuttle buses providing transport to the rental location. Even if you're not good at English, having a rental agreement makes the process easier. There are no hidden fees, but if the car has issues like broken glass, it's better to switch to another vehicle. For instance, I encountered a cracked side window that kept worsening, and it was troublesome to exchange the car since smaller rental outlets typically can't handle vehicle swaps. You'll need to visit a larger airport branch for such replacements. Fortunately, I managed to exchange the car for a Jeep Grand Cherokee at Las Vegas Airport. Also, remember that the rental time cannot be more than 30 minutes earlier or later than scheduled—otherwise, you'll be charged an extra day's fee.
