Naha Kokusai Dori vs Renting car and staying up north

I would really prefer not to rent a car (especially since most hotels on the strip dont have parking) but to get to places like Okinawa world and pokemon center it looks like ill have to unless I wanna waste money on long taxi rides. I was planning on staying on Naha Kokusai Dori and doing day trips on the ferry but now I'm thinking I should rent a car and stay somewhere with parking (staying 5 days)
