All you’ll need to bring is your driver's license or photo identification with address, & a credit or debit card to authorize the security deposit + Fuel Charge ($500 per jet ski). That charge will be canceled when the units are returned minus fuel. You’ll want to bring anything you’ll want on the water, the Jet Skis have storage to hold towels, bags, & phones. They are water resistant but the possibility of water getting in exists, so we recommend placing your phone & other electronics in a plastic bag.
