Yes, golf carts are treated just like any other motor vehicle and thus must pay to park. Pay-to-Park season is March 1st-October 31st from 9AM-5PM at a rate of $2.00 per hour. The city has created a website that contains more information on how to pay for parking: https://www.parknorthmyrtlebeach.com/
In addition to keeping the key with you at all times, the carts come with a cable lock that can be looped through the steering wheel and locked.
Electric carts need to be recharged each night which requires a standard electric outlet and battery charger (provided). We can also supply an extension cord if needed. They are quiet and can go about 15 miles on a full charge. If you will be driving the cart a lot, we recommend charging them anytime you are not using them. Gas carts are louder, but come with a full tank of gas that will last about 100 miles and does not have to be refilled at the end of the rental. Gas carts also handle hills better.
