When you go on vacation and see a big body of water, the experience can be bittersweet if you aren't prepared to fully enjoy it. Fortunately, if you're in an area with plenty of water and a lot of tourists, you have options for rectifying this situation. These options don't involve spending thousands of dollars on new boating equipment, or simply taking a tour on a slow catamaran. Instead, you can rent jet skis and get out there at a relatively low cost.
