How much is it for a 15 yr old to rent a cart? And how long is your rental time? What do you need to bring with you?

School ID might work but I'm not 100% sure on that.

They spell it out super well in their website: https://www.pacificgp.com/arrive-and-drive-2/. There parent/guardian will need to be present. And then they just say ID may be required, doesn't specify government issued. Each session is 13 minutes.

I ment in the way of identification. I wanted to bring my brother and he doesn't have an id card, he's only 15

It has been awhile since I have been there so I am not too sure about how much it is or how long, but as far as what you need, they provide everything. Helmets, helmet liners, and a safety course. I would just reccomend long pants and close toes shoes.
