As with renters of age (over 25), you’ll need to present all required qualifying documents (driver license, credit/debit card and proof of auto insurance). If you are under 21, you will need to hold at least an auto liability policy in place under your name, we will not be able to sell you insurance. In addition to any rental rate, an underage fee will be applied. The daily charge is $18 for ages between the age of 18 – 21, and $10 for ages between 22-24.
